From 9ec3b77e11b9398ab40b492c4fde7d8aac04a718 Mon Sep 17 00:00:00 2001 From: Dmitry Adamushko Date: Fri, 25 Jan 2008 21:08:21 +0100 Subject: [PATCH] sched: no need for 'affine wakeup' balancing No need to do a check for 'affine wakeup and passive balancing possibilities' in select_task_rq_fair() when task_cpu(p) == this_cpu. I guess, this part got missed upon introduction of per-sched_class select_task_rq() in try_to_wake_up().
