Subject: [RFC PATCH 4/7] sched/cpufreq: Move up sugov_cpu_is_busy()
Date: Wed, 8 May 2019 18:42:58 +0100 [thread overview]
Message-ID: <20190508174301.4828-5-douglas.raillard@arm.com> (raw)

In-Reply-To: <20190508174301.4828-1-douglas.raillard@arm.com>
From: Douglas RAILLARD <douglas.raillard@arm.com>
Move sugov_cpu_is_busy() static function of cpufreq_schedutil.c higher
in the file so it can be used by other functions.
