Hmm yes ..I am surprised we arent doing a synhronize_rcu in cpuset_rmdir() before dropping the dentry. Did you want to send a patch for that?
Currently cpuset_exit() isn't in a rcu section so it wouldn't help. But this ceases to be a problem if we don't leave the refcount dropping in cpuset_exit() where it is currently - it doesn't drop the refcount until it's holding manage_mutex, at which point it's safe to hold a cpuset reference with a refcount of 0.
