Hello, Linus.
cgroup fixes for v4.5-rc3.
* 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.
Thanks.
