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.
