Pull cgroup fix from Tejun Heo:
 "One late fix for cgroup.

  I was waiting for another set of fixes for a long-standing obscure
   cpuset bug but am not sure whether they'll be ready before v3.17
  release.  This one is a simple fix for a mutex unlock balance bug in
  an allocation failure path in pidlist_array_load().

  The bug was introduced in v3.14 and the fix is tagged for -stable"
