Subject[PATCH 3/3] sched/autogroup: Change autogroup_path() into a static inline function
Date
cfs_rq_tg_path() uses, besides cgroup_path(), autogroup_path() to
format the path of a taskgroup or autogroup respectively.

Provide autogroup_path() as a static inline function like cgroup_path()
so cfs_rq_tg_path() (from a tp-2-te converter) can use both in a kernel
module build.
