Oleg Nesterov 8e5bfa8c1f sched/autogroup: Do not use autogroup->tg in zombie threads ... Exactly because for_each_thread() in autogroup_move_group() can't see it and update its ->sched_task_group before _put() and possibly free(). So the exiting task needs another sched_move_task() before exit_notify() and we need to re-introduce the PF_EXITING (or similar) check removed by the previous change for another reason.
