Subject: [PATCH 1/4] sched/pelt: Remove redundant cap_scale() definition
Date: Wed, 3 Jun 2020 10:03:01 +0200 [thread overview]
Message-ID: <20200603080304.16548-2-dietmar.eggemann@arm.com> (raw)
In-Reply-To: <20200603080304.16548-1-dietmar.eggemann@arm.com>
Besides in PELT cap_scale() is used in the Deadline scheduler class for
scale-invariant bandwidth enforcement.
Remove the cap_scale() definition in kernel/sched/pelt.c and keep the
one in kernel/sched/sched.h.
