Oleg Nesterov 1a43a14a5b sched: Fix schedule_tail() to disable preemption ... finish_task_switch() enables preemption, so post_schedule(rq) can be called on the wrong (and even dead) CPU. Afaics, nothing really bad can happen, but in this case we can wrongly clear rq->post_schedule on that CPU. And this simply looks wrong in any case.
