Tetsuo Handa 1117984b6e locking/lockdep: Use for_each_process_thread() for debug_show_all_locks() ... debug_show_all_locks() tries to grab the tasklist_lock for two seconds, but calling while_each_thread() without tasklist_lock held is not safe. See the following commit for more information: 4449a51a7c281602 ("vm_is_stack: use for_each_thread() rather then buggy while_each_thread()") Change debug_show_all_locks() from "do_each_thread()/while_each_thread() with possibility of missing tasklist_lock" to "for_each_process_thread() with RCU", and add a call to touch_all_softlockup_watchdogs() like show_state_filter() does.
