Subject: [PATCH 2/3] sched/uclamp: Rename uclamp_util_*() into uclamp_rq_util_*()
Date: Wed, 20 Nov 2019 17:55:32 +0000	[thread overview]
Message-ID: <20191120175533.4672-3-valentin.schneider@arm.com> (raw)
In-Reply-To: <20191120175533.4672-1-valentin.schneider@arm.com>

The current helpers return (CPU) rq utilization with uclamp restrictions
taken into account. As I'm about to introduce a task clamped utilization
variant, make it explicit that those deal with runqueues.
