Message-ID: <1311846203.3938.1555.camel@minggr.sh.intel.com> Date: Thu, 28 Jul 2011 17:43:23 +0800 From: Lin Ming <ming.m.lin@...el.com> To: Peter Zijlstra <a.p.zijlstra@...llo.nl>, mingo@...e.hu Cc: lkml <linux-kernel@...r.kernel.org> Subject: [PATCH] sched: Remove WAKEUP_PREEMPT feature check in entity_tick Currently, entity_tick calls check_preempt_tick if WAKEUP_PREEMPT feature is disabled. That's wrong. It should do that if the feature is enabled. And actually the check is duplicate because check_preempt_tick will do that. So just remove it from entity_tick.
