Subject: [PATCH -rt] sched: remove unneeded #if directive
Date: Fri, 17 Oct 2008 18:21:29 -0700 [thread overview]
Message-ID: <48F93A19.9070007@ct.jp.nec.com> (raw)
From: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com>
__cond_resched_spinlock() is in #ifdef CONFIG_PREEMPT_RT.
So the following line always true.
#if (defined(CONFIG_SMP) && defined(CONFIG_PREEMPT)) || defined(CONFIG_PREEMPT_RT)
