Why can't manage_mutex itself be used there (to serialize fork/exit callbacks against modification to hierarchy)? > Apart from that, yes, it may well be possible to move callback lock > entirely inside cpusets. Yes, that way only the hierarchy hosting cpusets takes the hit of double-locking. cpuset_subsys->create/destroy can take this additional lock inside cpuset.c. -- Regards, vatsa ------------------------------------------------------------------------- Take Surveys.
