Subject: [PATCH 7/9] sched: Make default_scale_freq_power() static
Date: Tue, 5 Mar 2013 16:07:11 +0800 [thread overview]
Message-ID: <5135A7AF.8010900@huawei.com> (raw)
In-Reply-To: <5135A736.8050104@huawei.com>
As default_scale_{freq,smt}_power() and update_rt_power() are used
in kernel/sched/fair.c only, annotate them as static functions.
