    Merge branch 'for-4.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
    
    Pull cgroup fixes from Tejun Heo:
     "The threadgroup locking changes which went in during 4.2 devel cycle
      added write locking of a percpu_rwsem in cgroup task migration path;
      unfortunately, that involved expedited rcu syncing which turned out to
      be too slow and heavy for certain workloads.  The patchset which is
      dependent on this one didn't get committed during that devel cycle, so
      these two patches can be reverted safely.
    
      Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
      lighter.  The reported issue goes away with Oleg's reworked
      percpu_rwsem and I'll reapply these patches on the for-4.4 branch so
      that they can land together with Oleg's changes"
    
    * 'for-4.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
      Revert "sched, cgroup: replace signal_struct->group_rwsem with a global percpu_rwsem"
      Revert "cgroup: simplify threadgroup locking"
