Stephen Dickey 18695a1200 Revert "cgroup/cpuset: Convert cpuset_mutex to percpu_rwsem" ... This reverts commit 1243dc518c. percpu_rwsem is an rcu based lock. Under loaded conditions this lock will require that each cpu perform a switch, causing exessive delays with long-running tasks on those CPUs. In the case of hotplug/pause, this can slow down the ability to activate/deactivate a CPU. Revert the change from cpuset_mutex to percpu_rwsem, to eliminate that overhead, and revert to a global lock.
