From 3150398626466c6cc626732f60bc901d58f40677 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 12 Sep 2013 15:10:31 +0200 Subject: [PATCH] sched: Remove {set,clear}_need_resched Preemption semantics are going to change which mandate a change. All DRM usage sites are already broken and will not be affected (much) by this change. DRM people are aware and will remove the last few stragglers. For now, leave an empty stub that generates a warning, once all users are gone we can remove this.
