Merge branch 'for-4.5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup

Browse Source 
Pull cgroup fixes from Tejun Heo:

 - The destruction path of cgroup objects are asynchronous and
   multi-staged and some of them ended up destroying parents before
   children leading to failures in cpu and memory controllers.  Ensure
   that parents are always destroyed after children.

 - cpuset mm node migration was performed synchronously while holding
   threadgroup and cgroup mutexes and the recent threadgroup locking
   update resulted in a possible deadlock.  The migration is best effort
   and shouldn't have been performed under those locks to begin with.
   Made asynchronous.

 - Minor documentation fix.
