    Pull cpuset changes from Tejun Heo:
     - Synchornization has seen a lot of changes with focus on decoupling
       cpuset synchronization from cgroup internal locking.
       After this change, there only remain a couple of mostly trivial
       dependencies on cgroup_lock outside cgroup core proper.  cgroup_lock
       is scheduled to be unexported in this devel cycle.
       This will finally remove the fragile locking order around cgroup
       (cgroup locking wants to / should be one of the outermost but yet has
       been acquired from deep inside individual controllers).
     - At this point, Li is most knowlegeable with cpuset and taking over
       the maintainership of cpuset.
