This feature lets CPU scheduler recognize task groups and control CPU
bandwidth allocation to such task groups.
+ In order to create a group from arbitrary set of processes, use
+ CONFIG_CGROUPS. (See Control Group support.)
config FAIR_GROUP_SCHED
bool "Group scheduling for SCHED_OTHER"
This option allows you to create arbitrary task groups
using the "cgroup" pseudo filesystem and control
the cpu bandwidth allocated to each such task group.

sure you need the memory resource controller. Even when you enable
this, you can set "cgroup_disable=memory" at your boot option to
disable memory resource controller and you can avoid overheads.
- (and lose benefits of memory resource contoller)
+ (and lose benefits of memory resource controller)
This config option also selects MM_OWNER config option, which
could in turn add some fork/exit overhead.
+config CGROUP_MEM_RES_CTLR_SWAP
+ bool "Memory Resource Controller Swap Extension(EXPERIMENTAL)"
+ depends on CGROUP_MEM_RES_CTLR && SWAP && EXPERIMENTAL
+ help
+ Add swap management feature to memory resource controller. When you
+ enable this, you can limit mem+swap usage per cgroup. In other words,
+ when you disable this, memory resource controller has no cares to
+ usage of swap...a process can exhaust all of the swap. This extension
+ is useful when you want to avoid exhaustion swap but this itself
+ adds more overheads and consumes memory for remembering information.
+ Especially if you use 32bit system or small memory system, please
+ be careful about enabling this. When memory resource controller
+ is disabled by boot option, this will be automatically disabled and
+ there will be no overhead from this. Even when you set this config=y,
+ if boot option "noswapaccount" is set, swap will not be accounted.
