Subject: [patch v7 2/8] sched: move few runnable tg variables into CONFIG_SMP
Date: Thu, 30 May 2013 15:01:58 +0800 [thread overview]
Message-ID: <1369897324-16646-3-git-send-email-alex.shi@intel.com> (raw)
In-Reply-To: <1369897324-16646-1-git-send-email-alex.shi@intel.com>
The following 2 variables only used under CONFIG_SMP, so better to move
their definiation into CONFIG_SMP too.
atomic64_t load_avg;
atomic_t runnable_avg;
