Merge branch 'for-3.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj...

Pull cgroup fixes from Tejun Heo:
 "Quite a few fixes this time.

  Three locking fixes, all marked for -stable.  A couple error path
  fixes and some misc fixes.  Hugh found a bug in memcg offlining
  sequence and we thought we could fix that from cgroup core side but
  that turned out to be insufficient and got reverted.  A different fix
  has been applied to -mm"
