I think the problem here is that we don't have "you're committing to creation of a new cgroup" callback and thus subsystem can't synchronize locally against cgroup creation. For task migration ->attach() does that but cgroup creation may fail after ->create() succeeded so that doesn't work. We'll probably need to add ->post_create() which is invoked after creation is complete. Li?
