I only glanced the patch description but the problem I'm trying to solve is locking - currently we don't have a place where a controller can tell a cgroup is becoming online; thus it has nothing to synchronized against and tell that a cgroup is alive or not. As for css_id allocation, maybe you can deal with that in ->post_create() or maybe we can allocate css_id earlier (but where would it be stored?). I'll look into it.
Thanks.
