    To switch off group scheduling completely, please set CONFIG_GROUP_SCHED
    to off.

    If you wish to have cgroup based group scheduling, you need to
    set CONFIG_CGROUP_SCHED on (and if required CONFIG_FAIR_GROUP_SCHED for
    CFS group scheduling and CONFIG_RT_GROUP_SCHED for RT group scheduling)
