2 objects are used.
2.4 /proc/sys/vm - The virtual memory subsystem
-----------------------------------------------
-The files in this directory can be used to tune the operation of the virtual
-memory (VM) subsystem of the Linux kernel.
-
-vfs_cache_pressure
-------------------
-
-Controls the tendency of the kernel to reclaim the memory which is used for
-caching of directory and inode objects.
-
-At the default value of vfs_cache_pressure=100 the kernel will attempt to
-reclaim dentries and inodes at a "fair" rate with respect to pagecache and
-swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer
-to retain dentry and inode caches. Increasing vfs_cache_pressure beyond 100
-causes the kernel to prefer to reclaim dentries and inodes.
-
-dirty_background_bytes
-----------------------
-
-Contains the amount of dirty memory at which the pdflush background writeback
-daemon will start writeback.
-
-If dirty_background_bytes is written, dirty_background_ratio becomes a function
-of its value (dirty_background_bytes / the amount of dirtyable system memory).
-
-dirty_background_ratio
-----------------------
-
-Contains, as a percentage of the dirtyable system memory (free pages + mapped
-pages + file cache, not including locked pages and HugePages), the number of
-pages at which the pdflush background writeback daemon will start writing out
-dirty data.
-
-If dirty_background_ratio is written, dirty_background_bytes becomes a function
-of its value (dirty_background_ratio * the amount of dirtyable system memory).
-
-dirty_bytes
------------
-
-Contains the amount of dirty memory at which a process generating disk writes
-will itself start writeback.
-
-If dirty_bytes is written, dirty_ratio becomes a function of its value
-(dirty_bytes / the amount of dirtyable system memory).
-
-dirty_ratio
------------
-
-Contains, as a percentage of the dirtyable system memory (free pages + mapped
-pages + file cache, not including locked pages and HugePages), the number of
-pages at which a process which is generating disk writes will itself start
-writing out dirty data.
-
-If dirty_ratio is written, dirty_bytes becomes a function of its value
-(dirty_ratio * the amount of dirtyable system memory).
-
-dirty_writeback_centisecs
--------------------------
-
-The pdflush writeback daemons will periodically wake up and write `old' data
-out to disk. This tunable expresses the interval between those wakeups, in
-100'ths of a second.
-
-Setting this to zero disables periodic writeback altogether.
-
-dirty_expire_centisecs
-----------------------
-
-This tunable is used to define when dirty data is old enough to be eligible
-for writeout by the pdflush daemons. It is expressed in 100'ths of a second.
-Data which has been dirty in-memory for longer than this interval will be
-written out next time a pdflush daemon wakes up.
-
-highmem_is_dirtyable
---------------------
-
-Only present if CONFIG_HIGHMEM is set.
-
-This defaults to 0 (false), meaning that the ratios set above are calculated
-as a percentage of lowmem only. This protects against excessive scanning
-in page reclaim, swapping and general VM distress.
-
-Setting this to 1 can be useful on 32 bit machines where you want to make
-random changes within an MMAPed file that is larger than your available
-lowmem without causing large quantities of random IO. Is is safe if the
-behavior of all programs running on the machine is known and memory will
-not be otherwise stressed.
-
-legacy_va_layout
-----------------
-
-If non-zero, this sysctl disables the new 32-bit mmap mmap layout - the kernel
-will use the legacy (2.4) layout for all processes.
-
-lowmem_reserve_ratio
----------------------
-
-For some specialised workloads on highmem machines it is dangerous for
-the kernel to allow process memory to be allocated from the "lowmem"
-zone. This is because that memory could then be pinned via the mlock()
-system call, or by unavailability of swapspace.
-
-And on large highmem machines this lack of reclaimable lowmem memory
-can be fatal.
-
-So the Linux page allocator has a mechanism which prevents allocations
-which _could_ use highmem from using too much lowmem. This means that
-a certain amount of lowmem is defended from the possibility of being
-captured into pinned user memory.
-
-(The same argument applies to the old 16 megabyte ISA DMA region. This
-mechanism will also defend that region from allocations which could use
-highmem or lowmem).
-
-The `lowmem_reserve_ratio' tunable determines how aggressive the kernel is
-in defending these lower zones.
-
-If you have a machine which uses highmem or ISA DMA and your
-applications are using mlock(), or if you are running with no swap then
-you probably should change the lowmem_reserve_ratio setting.
-
-The lowmem_reserve_ratio is an array. You can see them by reading this file.
--
-% cat /proc/sys/vm/lowmem_reserve_ratio
-256 256 32
--
-Note: # of this elements is one fewer than number of zones. Because the highest
- zone's value is not necessary for following calculation.
-
-But, these values are not used directly. The kernel calculates # of protection
-pages for each zones from them. These are shown as array of protection pages
-in /proc/zoneinfo like followings. (This is an example of x86-64 box).
-Each zone has an array of protection pages like this.
-
--
-Node 0, zone DMA
- pages free 1355
- min 3
- low 3
- high 4
- :
- :
- numa_other 0
- protection: (0, 2004, 2004, 2004)
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- pagesets
- cpu: 0 pcp: 0
- :
--
-These protections are added to score to judge whether this zone should be used
-for page allocation or should be reclaimed.
-
-In this example, if normal pages (index=2) are required to this DMA zone and
-pages_high is used for watermark, the kernel judges this zone should not be
-used because pages_free(1355) is smaller than watermark + protection[2]
-(4 + 2004 = 2008). If this protection value is 0, this zone would be used for
-normal page requirement. If requirement is DMA zone(index=0), protection[0]
-(=0) is used.
-
-zone[i]'s protection[j] is calculated by following expression.
-
-(i < j):
- zone[i]->protection[j]
- = (total sums of present_pages from zone[i+1] to zone[j] on the node)
- / lowmem_reserve_ratio[i];
-(i = j):
- (should not be protected. = 0;
-(i > j):
- (not necessary, but looks 0)
-
-The default values of lowmem_reserve_ratio[i] are
- 256 (if zone[i] means DMA or DMA32 zone)
- 32 (others).
-As above expression, they are reciprocal number of ratio.
-256 means 1/256. # of protection pages becomes about "0.39%" of total present
-pages of higher zones on the node.
-
-If you would like to protect more pages, smaller values are effective.
-The minimum value is 1 (1/1 -> 100%).
-
-page-cluster
-------------
-
-page-cluster controls the number of pages which are written to swap in
-a single attempt. The swap I/O size.
-
-It is a logarithmic value - setting it to zero means "1 page", setting
-it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
-
-The default value is three (eight pages at a time). There may be some
-small benefits in tuning this to a different value if your workload is
-swap-intensive.
-
-overcommit_memory
------------------
-
-Controls overcommit of system memory, possibly allowing processes
-to allocate (but not use) more memory than is actually available.
-
-
-0 - Heuristic overcommit handling. Obvious overcommits of
- address space are refused. Used for a typical system. It
- ensures a seriously wild allocation fails while allowing
- overcommit to reduce swap usage. root is allowed to
- allocate slightly more memory in this mode. This is the
- default.
-
-1 - Always overcommit. Appropriate for some scientific
- applications.
-
-2 - Don't overcommit. The total address space commit
- for the system is not permitted to exceed swap plus a
- configurable percentage (default is 50) of physical RAM.
- Depending on the percentage you use, in most situations
- this means a process will not be killed while attempting
- to use already-allocated memory but will receive errors
- on memory allocation as appropriate.
-
-overcommit_ratio
-----------------
-
-Percentage of physical memory size to include in overcommit calculations
-(see above.)
-
-Memory allocation limit = swapspace + physmem * (overcommit_ratio / 100)
-
- swapspace = total size of all swap areas
- physmem = size of physical memory in system
-
-nr_hugepages and hugetlb_shm_group
-----------------------------------
-
-nr_hugepages configures number of hugetlb page reserved for the system.
-
-hugetlb_shm_group contains group id that is allowed to create SysV shared
-memory segment using hugetlb page.
-
-hugepages_treat_as_movable
---------------------------
-
-This parameter is only useful when kernelcore= is specified at boot time to
-create ZONE_MOVABLE for pages that may be reclaimed or migrated. Huge pages
-are not movable so are not normally allocated from ZONE_MOVABLE. A non-zero
-value written to hugepages_treat_as_movable allows huge pages to be allocated
-from ZONE_MOVABLE.
-
-Once enabled, the ZONE_MOVABLE is treated as an area of memory the huge
-pages pool can easily grow or shrink within. Assuming that applications are
-not running that mlock() a lot of memory, it is likely the huge pages pool
-can grow to the size of ZONE_MOVABLE by repeatedly entering the desired value
-into nr_hugepages and triggering page reclaim.
-
-laptop_mode
------------
-
-laptop_mode is a knob that controls "laptop mode". All the things that are
-controlled by this knob are discussed in Documentation/laptops/laptop-mode.txt.
-
-block_dump
-----------
-
-block_dump enables block I/O debugging when set to a nonzero value. More
-information on block I/O debugging is in Documentation/laptops/laptop-mode.txt.
-
-swap_token_timeout
-------------------
-
-This file contains valid hold time of swap out protection token. The Linux
-VM has token based thrashing control mechanism and uses the token to prevent
-unnecessary page faults in thrashing situation. The unit of the value is
-second. The value would be useful to tune thrashing behavior.
-
-drop_caches
------------
-
-Writing to this will cause the kernel to drop clean caches, dentries and
-inodes from memory, causing that memory to become free.
-
-To free pagecache:
- echo 1 > /proc/sys/vm/drop_caches
-To free dentries and inodes:
- echo 2 > /proc/sys/vm/drop_caches
-To free pagecache, dentries and inodes:
- echo 3 > /proc/sys/vm/drop_caches
-
-As this is a non-destructive operation and dirty objects are not freeable, the
-user should run `sync' first.
+Please see: Documentation/sysctls/vm.txt for a description of these
+entries.

+dirty_background_bytes
-This value contains a flag that enables memory overcommitment.
+Contains the amount of dirty memory at which the pdflush background writeback

+dirty_background_ratio
-This feature can be very useful because there are a lot of
-programs that malloc() huge amounts of memory "just-in-case"

-The default value is 0.
+==============================================================
-See Documentation/vm/overcommit-accounting and
-security/commoncap.c::cap_vm_enough_memory() for more information.

+
+Contains the amount of dirty memory at which a process generating disk writes

==============================================================
-overcommit_ratio:
+dirty_expire_centisecs
-When overcommit_memory is set to 2, the committed address
-space is not permitted to exceed swap plus this percentage
-of physical RAM. See above.
+This tunable is used to define when dirty data is old enough to be eligible
+for writeout by the pdflush daemons. It is expressed in 100'ths of a second.
+Data which has been dirty in-memory for longer than this interval will be

==============================================================
-page-cluster:
+dirty_writeback_centisecs
-The Linux VM subsystem avoids excessive disk seeks by reading
-multiple pages on a page fault. The number of pages it reads
-is dependent on the amount of memory in your machine.
+The pdflush writeback daemons will periodically wake up and write `old' data
+out to disk. This tunable expresses the interval between those wakeups, in
+100'ths of a second.
-The number of pages the kernel reads in at once is equal to
-2 ^ page-cluster. Values above 2 ^ 5 don't make much sense
-for swap because we only cluster swap data in 32-page groups.
+Setting this to zero disables periodic writeback altogether.
==============================================================
-max_map_count:
+drop_caches
-This file contains the maximum number of memory map areas a process
-may have. Memory map areas are used as a side-effect of calling
-malloc, directly by mmap and mprotect, and also when loading shared
-libraries.
+Writing to this will cause the kernel to drop clean caches, dentries and
+inodes from memory, causing that memory to become free.
-While most applications need less than a thousand maps, certain
-programs, particularly malloc debuggers, may consume lots of them,
-e.g., up to one or two maps per allocation.

-The default value is 65536.
+As this is a non-destructive operation and dirty objects are not freeable, the
+user should run `sync' first.
==============================================================
-min_free_kbytes:
+hugepages_treat_as_movable
-This is used to force the Linux VM to keep a minimum number
-of kilobytes free. The VM uses this number to compute a pages_min
-value for each lowmem zone in the system. Each lowmem zone gets
-a number of reserved free pages based proportionally on its size.
+This parameter is only useful when kernelcore= is specified at boot time to
+create ZONE_MOVABLE for pages that may be reclaimed or migrated. Huge pages
+are not movable so are not normally allocated from ZONE_MOVABLE. A non-zero
+value written to hugepages_treat_as_movable allows huge pages to be allocated
+from ZONE_MOVABLE.
-Some minimal amount of memory is needed to satisfy PF_MEMALLOC
-allocations; if you set this to lower than 1024KB, your system will
-become subtly broken, and prone to deadlock under high loads.
-
-Setting this too high will OOM your machine instantly.
+Once enabled, the ZONE_MOVABLE is treated as an area of memory the huge
+pages pool can easily grow or shrink within. Assuming that applications are
+not running that mlock() a lot of memory, it is likely the huge pages pool
+can grow to the size of ZONE_MOVABLE by repeatedly entering the desired value
+into nr_hugepages and triggering page reclaim.
==============================================================
-percpu_pagelist_fraction
+hugetlb_shm_group
-This is the fraction of pages at most (high mark pcp->high) in each zone that
-are allocated for each per cpu page list. The min value for this is 8. It
-means that we don't allow more than 1/8th of pages in each zone to be
-allocated in any single per_cpu_pagelist. This entry only changes the value
-of hot per cpu pagelists. User can specify a number like 100 to allocate
-1/100th of each zone to each per cpu page list.
+hugetlb_shm_group contains group id that is allowed to create SysV
+shared memory segment using hugetlb page.
-The batch value of each per cpu pagelist is also updated as a result. It is
-set to pcp->high/4. The upper limit of batch is (PAGE_SHIFT * 8)
+==============================================================
-The initial value is zero. Kernel does not use this value at boot time to set
-the high water marks for each per cpu page list.
+laptop_mode
-===============================================================
+laptop_mode is a knob that controls "laptop mode". All the things that are
+controlled by this knob are discussed in Documentation/laptops/laptop-mode.txt.
-zone_reclaim_mode:
+==============================================================
-Zone_reclaim_mode allows someone to set more or less aggressive approaches to
-reclaim memory when a zone runs out of memory. If it is set to zero then no
-zone reclaim occurs. Allocations will be satisfied from other zones / nodes
-in the system.
+legacy_va_layout
-This is value ORed together of
+If non-zero, this sysctl disables the new 32-bit mmap mmap layout - the kernel
+will use the legacy (2.4) layout for all processes.
-1 = Zone reclaim on
-2 = Zone reclaim writes dirty pages out
-4 = Zone reclaim swaps pages
+==============================================================
-zone_reclaim_mode is set during bootup to 1 if it is determined that pages
-from remote zones will cause a measurable performance reduction. The
-page allocator will then reclaim easily reusable pages (those page
-cache pages that are currently not used) before allocating off node pages.
+lowmem_reserve_ratio
+
+For some specialised workloads on highmem machines it is dangerous for
+the kernel to allow process memory to be allocated from the "lowmem"
+zone. This is because that memory could then be pinned via the mlock()
+system call, or by unavailability of swapspace.
+
+And on large highmem machines this lack of reclaimable lowmem memory
+can be fatal.
+
+So the Linux page allocator has a mechanism which prevents allocations
+which _could_ use highmem from using too much lowmem. This means that
+a certain amount of lowmem is defended from the possibility of being
+captured into pinned user memory.
+
+(The same argument applies to the old 16 megabyte ISA DMA region. This
+mechanism will also defend that region from allocations which could use
+highmem or lowmem).
+
+The `lowmem_reserve_ratio' tunable determines how aggressive the kernel is
+in defending these lower zones.
+
+If you have a machine which uses highmem or ISA DMA and your
+applications are using mlock(), or if you are running with no swap then
+you probably should change the lowmem_reserve_ratio setting.
+
+The lowmem_reserve_ratio is an array. You can see them by reading this file.
+-
+% cat /proc/sys/vm/lowmem_reserve_ratio
+256 256 32
+-
+Note: # of this elements is one fewer than number of zones. Because the highest
+ zone's value is not necessary for following calculation.
+
+But, these values are not used directly. The kernel calculates # of protection
+pages for each zones from them. These are shown as array of protection pages
+in /proc/zoneinfo like followings. (This is an example of x86-64 box).
+Each zone has an array of protection pages like this.
+
+-
+Node 0, zone DMA
+ pages free 1355
+ min 3
+ low 3
+ high 4
+ :
+ :
+ numa_other 0
+ protection: (0, 2004, 2004, 2004)
+ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+ pagesets
+ cpu: 0 pcp: 0
+ :
+-
+These protections are added to score to judge whether this zone should be used
+for page allocation or should be reclaimed.
+
+In this example, if normal pages (index=2) are required to this DMA zone and
+pages_high is used for watermark, the kernel judges this zone should not be
+used because pages_free(1355) is smaller than watermark + protection[2]
+(4 + 2004 = 2008). If this protection value is 0, this zone would be used for
+normal page requirement. If requirement is DMA zone(index=0), protection[0]
+(=0) is used.
+
+zone[i]'s protection[j] is calculated by following expression.
+
+(i < j):
+ zone[i]->protection[j]
+ = (total sums of present_pages from zone[i+1] to zone[j] on the node)
+ / lowmem_reserve_ratio[i];
+(i = j):
+ (should not be protected. = 0;
+(i > j):
+ (not necessary, but looks 0)
+
+The default values of lowmem_reserve_ratio[i] are
+ 256 (if zone[i] means DMA or DMA32 zone)
+ 32 (others).
+As above expression, they are reciprocal number of ratio.
+256 means 1/256. # of protection pages becomes about "0.39%" of total present
+pages of higher zones on the node.
+
+If you would like to protect more pages, smaller values are effective.
+The minimum value is 1 (1/1 -> 100%).
-It may be beneficial to switch off zone reclaim if the system is
-used for a file server and all of memory should be used for caching files
-from disk. In that case the caching effect is more important than
-data locality.
+==============================================================
-Allowing zone reclaim to write out pages stops processes that are
-writing large amounts of data from dirtying pages on other nodes. Zone
-reclaim will write out dirty pages if a zone fills up and so effectively
-throttle the process. This may decrease the performance of a single process
-since it cannot use all of system memory to buffer the outgoing writes
-anymore but it preserve the memory on other nodes so that the performance
-of other processes running on other nodes will not be affected.
+max_map_count:
-Allowing regular swap effectively restricts allocations to the local
-node unless explicitly overridden by memory policies or cpuset
-configurations.
+This file contains the maximum number of memory map areas a process
+may have. Memory map areas are used as a side-effect of calling
+malloc, directly by mmap and mprotect, and also when loading shared
+libraries.
-=============================================================
+While most applications need less than a thousand maps, certain
+programs, particularly malloc debuggers, may consume lots of them,
+e.g., up to one or two maps per allocation.
-min_unmapped_ratio:
+The default value is 65536.
-This is available only on NUMA kernels.
+==============================================================
-A percentage of the total pages in each zone. Zone reclaim will only
-occur if more than this percentage of pages are file backed and unmapped.
-This is to insure that a minimal amount of local pages is still available for
-file I/O even if the node is overallocated.
+min_free_kbytes:
-The default is 1 percent.
+This is used to force the Linux VM to keep a minimum number
+of kilobytes free. The VM uses this number to compute a pages_min
+value for each lowmem zone in the system. Each lowmem zone gets
+a number of reserved free pages based proportionally on its size.
+
+Some minimal amount of memory is needed to satisfy PF_MEMALLOC
+allocations; if you set this to lower than 1024KB, your system will
+become subtly broken, and prone to deadlock under high loads.
+
+Setting this too high will OOM your machine instantly.
=============================================================
=============================================================
-panic_on_oom
+min_unmapped_ratio:
-This enables or disables panic on out-of-memory feature.
+This is available only on NUMA kernels.
-If this is set to 0, the kernel will kill some rogue process,
-called oom_killer. Usually, oom_killer can kill rogue processes and
-system will survive.
+A percentage of the total pages in each zone. Zone reclaim will only
+occur if more than this percentage of pages are file backed and unmapped.
+This is to insure that a minimal amount of local pages is still available for
+file I/O even if the node is overallocated.
-If this is set to 1, the kernel panics when out-of-memory happens.
-However, if a process limits using nodes by mempolicy/cpusets,
-and those nodes become memory exhaustion status, one process
-may be killed by oom-killer. No panic occurs in this case.
-Because other nodes' memory may be free. This means system total status
-may be not fatal yet.
+The default is 1 percent.
-If this is set to 2, the kernel panics compulsorily even on the
-above-mentioned.
+==============================================================
-The default value is 0.
-1 and 2 are for failover of clustering. Please select either
-according to your policy of failover.
+mmap_min_addr
-=============================================================
+This file indicates the amount of address space which a user process will
+be restricted from mmaping. Since kernel null dereference bugs could
+accidentally operate based on the information in the first couple of pages
+of memory userspace processes should not be allowed to write to them. By
+default this value is set to 0 and no protections will be enforced by the
+security module. Setting this value to something like 64k will allow the
+vast majority of applications to work correctly and provide defense in depth
+against future potential kernel bugs.
-oom_dump_tasks
+==============================================================
-Enables a system-wide task dump (excluding kernel threads) to be
-produced when the kernel performs an OOM-killing and includes such
-information as pid, uid, tgid, vm size, rss, cpu, oom_adj score, and
-name. This is helpful to determine why the OOM killer was invoked
-and to identify the rogue task that caused it.
+nr_hugepages
-If this is set to zero, this information is suppressed. On very
-large systems with thousands of tasks it may not be feasible to dump
-the memory state information for each one. Such systems should not
-be forced to incur a performance penalty in OOM conditions when the
-information may not be desired.
+Change the minimum size of the hugepage pool.
-If this is set to non-zero, this information is shown whenever the
-OOM killer actually kills a memory-hogging task.
+See Documentation/vm/hugetlbpage.txt
-The default value is 0.
+==============================================================
-=============================================================
+nr_overcommit_hugepages
-oom_kill_allocating_task
+Change the maximum size of the hugepage pool. The maximum is
+nr_hugepages + nr_overcommit_hugepages.
-This enables or disables killing the OOM-triggering task in
-out-of-memory situations.
+See Documentation/vm/hugetlbpage.txt
-If this is set to zero, the OOM killer will scan through the entire
-tasklist and select a task based on heuristics to kill. This normally
-selects a rogue memory-hogging task that frees up a large amount of
-memory when killed.
+==============================================================
-If this is set to non-zero, the OOM killer simply kills the task that
-triggered the out-of-memory condition. This avoids the expensive
-tasklist scan.
+nr_pdflush_threads
-If panic_on_oom is selected, it takes precedence over whatever value
-is used in oom_kill_allocating_task.
+The current number of pdflush threads. This value is read-only.
+The value changes according to the number of dirty pages in the system.
-The default value is 0.
+When neccessary, additional pdflush threads are created, one per second, up to
+nr_pdflush_threads_max.
==============================================================
-mmap_min_addr
+nr_trim_pages
-This file indicates the amount of address space which a user process will
-be restricted from mmaping. Since kernel null dereference bugs could
-accidentally operate based on the information in the first couple of pages
-of memory userspace processes should not be allowed to write to them. By
-default this value is set to 0 and no protections will be enforced by the
-security module. Setting this value to something like 64k will allow the
-vast majority of applications to work correctly and provide defense in depth
-against future potential kernel bugs.
+This is available only on NOMMU kernels.
+
+This value adjusts the excess page trimming behaviour of power-of-2 aligned
+NOMMU mmap allocations.
+
+A value of 0 disables trimming of allocations entirely, while a value of 1
+trims excess pages aggressively. Any value >= 1 acts as the watermark where
+trimming of allocations is initiated.
+
+The default value is 1.

+
+The default value is 0.
==============================================================
-nr_trim_pages
+overcommit_memory:
-This is available only on NOMMU kernels.
+This value contains a flag that enables memory overcommitment.
-This value adjusts the excess page trimming behaviour of power-of-2 aligned
-NOMMU mmap allocations.
+When this flag is 0, the kernel attempts to estimate the amount
+of free memory left when userspace requests more memory.
-A value of 0 disables trimming of allocations entirely, while a value of 1
-trims excess pages aggressively. Any value >= 1 acts as the watermark where
-trimming of allocations is initiated.
+When this flag is 1, the kernel pretends there is always enough
+memory until it actually runs out.
-The default value is 1.
+When this flag is 2, the kernel uses a "never overcommit"
+policy that attempts to prevent any overcommit of memory.
-See Documentation/nommu-mmap.txt for more information.
+This feature can be very useful because there are a lot of
+programs that malloc() huge amounts of memory "just-in-case"
+and don't use much of it.
+
+The default value is 0.
+
+See Documentation/vm/overcommit-accounting and
+security/commoncap.c::cap_vm_enough_memory() for more information.
+
+==============================================================
+
+overcommit_ratio:
+
+When overcommit_memory is set to 2, the committed address
+space is not permitted to exceed swap plus this percentage
+of physical RAM. See above.
+
+==============================================================
+
+page-cluster
+
+page-cluster controls the number of pages which are written to swap in
+a single attempt. The swap I/O size.
+
+It is a logarithmic value - setting it to zero means "1 page", setting
+it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
+
+The default value is three (eight pages at a time). There may be some
+small benefits in tuning this to a different value if your workload is
+swap-intensive.
+
+=============================================================
+
+panic_on_oom
+
+This enables or disables panic on out-of-memory feature.
+
+If this is set to 0, the kernel will kill some rogue process,
+called oom_killer. Usually, oom_killer can kill rogue processes and
+system will survive.
+
+If this is set to 1, the kernel panics when out-of-memory happens.
+However, if a process limits using nodes by mempolicy/cpusets,
+and those nodes become memory exhaustion status, one process
+may be killed by oom-killer. No panic occurs in this case.
+Because other nodes' memory may be free. This means system total status
+may be not fatal yet.
+
+If this is set to 2, the kernel panics compulsorily even on the
+above-mentioned.
+
+The default value is 0.
+1 and 2 are for failover of clustering. Please select either
+according to your policy of failover.
+
+=============================================================
+
+percpu_pagelist_fraction
+
+This is the fraction of pages at most (high mark pcp->high) in each zone that
+are allocated for each per cpu page list. The min value for this is 8. It
+means that we don't allow more than 1/8th of pages in each zone to be
+allocated in any single per_cpu_pagelist. This entry only changes the value
+of hot per cpu pagelists. User can specify a number like 100 to allocate
+1/100th of each zone to each per cpu page list.
+
+The batch value of each per cpu pagelist is also updated as a result. It is
+set to pcp->high/4. The upper limit of batch is (PAGE_SHIFT * 8)
+
+The initial value is zero. Kernel does not use this value at boot time to set
+the high water marks for each per cpu page list.
+
+==============================================================
+
+stat_interval
+
+The time interval between which vm statistics are updated. The default
+is 1 second.
+
+==============================================================
+
+swappiness
+
+This control is used to define how aggressive the kernel will swap
+memory pages. Higher values will increase agressiveness, lower values
+descrease the amount of swap.
+
+The default value is 60.
+
+==============================================================
+
+vfs_cache_pressure
+------------------
+
+Controls the tendency of the kernel to reclaim the memory which is used for
+caching of directory and inode objects.
+
+At the default value of vfs_cache_pressure=100 the kernel will attempt to
+reclaim dentries and inodes at a "fair" rate with respect to pagecache and
+swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer
+to retain dentry and inode caches. Increasing vfs_cache_pressure beyond 100
+causes the kernel to prefer to reclaim dentries and inodes.
+
+==============================================================
+
+zone_reclaim_mode:
+
+Zone_reclaim_mode allows someone to set more or less aggressive approaches to
+reclaim memory when a zone runs out of memory. If it is set to zero then no
+zone reclaim occurs. Allocations will be satisfied from other zones / nodes
+in the system.
+
+This is value ORed together of
+
+1 = Zone reclaim on
+2 = Zone reclaim writes dirty pages out
+4 = Zone reclaim swaps pages
+
+zone_reclaim_mode is set during bootup to 1 if it is determined that pages
+from remote zones will cause a measurable performance reduction. The
+page allocator will then reclaim easily reusable pages (those page
+cache pages that are currently not used) before allocating off node pages.
+
+It may be beneficial to switch off zone reclaim if the system is

Linux Magic System Request Key Hacks
Documentation for sysrq.c
-Last update: 2007-AUG-04
* What is the magic SysRq key?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a lock (you are also in an interrupt handler, which means don't sleep!), so
you must call __handle_sysrq_nolock instead.
+* When I hit a SysRq key combination only the header appears on the console?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Sysrq output is subject to the same console loglevel control as all
+other console output. This means that if the kernel was booted 'quiet'
+as is common on distro kernels the output may not appear on the actual
+console, even though it will appear in the dmesg buffer, and be accessible
+via the dmesg command and to the consumers of /proc/kmsg. As a specific
+exception the header line from the sysrq command is passed to all console
+consumers as if the current loglevel was maximum. If only the header
+is emitted it is almost certain that the kernel loglevel is too low.
+Should you require the output on the console channel then you will need
+to temporarily up the console loglevel using alt-sysrq-8 or:
+
+ echo 8 > /proc/sysrq-trigger
+
+Remember to return the loglevel to normal after triggering the sysrq
+command you are interested in.
+
* I have more questions, who can I ask?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And I'll answer any questions about the registration system you got, also
