If that is the case, I think we can push container_lock entirely inside cpuset.c and not have others exposed to this double-lock complexity. This is possible because cpuset.c (build on top of containers) still has cpuset->parent and walking cpuset->parent list safely can be made possible with a second lock which is local to only cpuset.c.
The callback mutex (which is what container_lock() actually locks) is also used to synchronize fork/exit against subsystem additions, in the event that some subsystem has registered fork or exit callbacks. We could probably have a separate subsystem_mutex for that instead. Apart from that, yes, it may well be possible to move callback lock entirely inside cpusets.
