HugePages_Rsvd is short for "reserved," and is the number of hugepages
for which a commitment to allocate from the pool has been made, but no
allocation has yet been made. It's vaguely analogous to overcommit.
+HugePages_Surp is short for "surplus," and is the number of hugepages in
+the pool above the value in /proc/sys/vm/nr_hugepages. The maximum
+number of surplus hugepages is controlled by
+/proc/sys/vm/nr_overcommit_hugepages.
/proc/filesystems should also show a filesystem of type "hugetlbfs" configured
in the kernel.

to put this command in one of the local rc init files. This will enable the
kernel to request huge pages early in the boot process (when the possibility
-of getting physical contiguous pages is still very high).
+of getting physical contiguous pages is still very high). In either
+case, adminstrators will want to verify the number of hugepages actually
+allocated by checking the sysctl or meminfo.
+
+/proc/sys/vm/nr_overcommit_hugepages indicates how large the pool of
+hugepages can grow, if more hugepages than /proc/sys/vm/nr_hugepages are
+requested by applications. echo'ing any non-zero value into this file
+indicates that the hugetlb subsystem is allowed to try to obtain
+hugepages from the buddy allocator, if the normal pool is exhausted. As
+these surplus hugepages go out of use, they are freed back to the buddy
+allocator.
+
+Caveat: Shrinking the pool via nr_hugepages while a surplus is in effect
+will allow the number of surplus huge pages to exceed the overcommit
+value, as the pool hugepages (which must have been in use for a surplus
+hugepages to be allocated) will become surplus hugepages. As long as
+this condition holds, however, no more surplus huge pages will be
+allowed on the system until one of the two sysctls are increased
+sufficiently, or the surplus huge pages go out of use and are freed.
If the user applications are going to request hugepages using mmap system
call, then it is required that system administrator mount a file system of
options, you can use [G|g]/[M|m]/[K|k] to represent giga/mega/kilo. For
example, size=2K has the same meaning as size=2048.
-read and write system calls are not supported on files that reside on hugetlb
-file systems.
+While read system calls are supported on files that reside on hugetlb
+file systems, write system calls are not.
Regular chown, chgrp, and chmod commands (with right permissions) could be
used to change the file attributes on hugetlbfs.

-*! Revision 1.9 2000/03/02 15:42:59 macce
-*! * Hack to make RTC work on all 2100/2400
-*!
-*! Revision 1.8 2000/02/23 16:59:18 torbjore
-*! added setup of R_GEN_CONFIG when RTC is connected to the generic port.
-*!
-*! Revision 1.7 2000/01/17 15:51:43 johana
-*! Added RTC_SET_CHARGE ioctl to enable trickle charger.
-*!
-*! Revision 1.6 1999/10/27 13:19:47 bjornw
-*! Added update_xtime_from_cmos which reads back the updated RTC into the kernel.
-*! /dev/rtc calls it now.
-*!
-*! Revision 1.5 1999/10/27 12:39:37 bjornw
-*! Disabled superuser check. Anyone can now set the time.
-*!
-*! Revision 1.4 1999/09/02 13:27:46 pkj
-*! Added shadow for R_PORT_PB_CONFIG.
-*! Renamed port_g_shadow to port_g_data_shadow.
-*!
-*! Revision 1.3 1999/09/02 08:28:06 pkj
-*! Made it possible to select either port PB or the generic port for the RST
-*! signal line to the DS1302 RTC.
-*! Also make sure the RST bit is configured as output on Port PB (if used).
-*!
-*! Revision 1.2 1999/09/01 14:47:20 bjornw
-*! Added support for /dev/rtc operations with ioctl RD_TIME and SET_TIME to read
-*! and set the date. Register as major 121.
-*!
-*! Revision 1.1 1999/09/01 09:45:29 bjornw
-*! Implemented a DS1302 RTC driver.
