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

This feature lets you explicitly allocate real CPU bandwidth
to users or control groups (depending on the "Basis for grouping tasks"
setting below. If enabled, it will also make it impossible to
schedule realtime tasks for non-root users until you allocate
realtime bandwidth for them.
See Documentation/scheduler/sched-rt-group.txt for more information.

This option will choose userid as the basis for grouping
tasks, thus providing equal CPU bandwidth to each user.
config CGROUP_SCHED

help
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.
Refer to Documentation/cgroups/cgroups.txt for more
information on "cgroup" pseudo filesystem.
