While not related to this patch, but per 3245d6acab9 (exit: fix race between wait_consider_task() and wait_task_zombie()), should we not *_ONCE() all things ->exit_state? I'm not really refering to a specific bug (much less here, where that race would not matter obviously), but if nothing else, for documentation -- and I doubt it would make any difference performance wise. Thanks, Davidlohr
