Andrew Morton d5f9f942c6 revert 'sched: redundant reschedule when set_user_nice() boosts a prio of a task from the "expired" array' ... Revert commit bd53f96ca5. Con says: This is no good, sorry. The one I saw originally was with the staircase deadline cpu scheduler in situ and was different. #define TASK_PREEMPTS_CURR(p, rq) \ ((p)->prio < (rq)->curr->prio) (((p)->prio < (rq)->curr->prio) && ((p)->array == (rq)->active)) This will fail to wake up a runqueue for a task that has been migrated to the expired array of a runqueue which is otherwise idle which can happen with smp balancing, Cc: Dmitry Adamushko <dmitry.adamushko@gmail.com> Cc: Con Kolivas <kernel@kolivas.org> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2007-05-08 20:41:15 -07:00
