    Subject[PATCH -tip 0/2] sched: Get group names back in /proc/sched_debug
    Hi,

    With autogroup patches, the group names got dropped off from
    /proc/sched_debug. Without group name info, it is difficult to figure out
    which cfs_rq or task belongs to which group in /proc/sched_debug output.

    This patchset brings back the group name and also adds autogroup names
    to /proc/sched_debug output.

    Before this patchset
    ====================
    # grep cfs_rq /proc/sched_debug
    cfs_rq[0]:
