This series consists of 2 independent cleanup patches. The first one
eliminates the tracking of the number of child partitions as that value
isn't that useful anymore simplifying the code. The second one change
callback_lock into raw_spinlock_t to reduce cpuset operation overhead in
a PREEMPT_RT setting.

Waiman Long (2):
  cgroup/cpuset: Don't track # of local child partitions
  cgroup/cpuset: Change callback_lock to raw_spinlock_t
