[GIT PULL] cgroup fixes for v4.5-rc3

Show all headers | View raw

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.
