From cdd2ab3de4301728b20efd6225681d3ff591a938 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 7 Sep 2009 18:12:06 +0200 Subject: [PATCH] sched: Remove short cut from select_task_rq_fair() select_task_rq_fair() incorrectly skips the wake_affine() logic, remove this. When prev_cpu == this_cpu, the code jumps straight to the wake_idle() logic, this doesn't give the wake_affine() logic the chance to pin the task to this cpu.
