Ensure that parents are always destroyed after children. * cpuset mm node migration was performed synchronously while holding threadgroup and cgroup mutexes and the recent threadgroup locking update resulted in a possible deadlock. The migration is best effort and shouldn't have been performed under those locks to begin with. Made asynchronous. * Minor documentation fix. Thanks.
