Subject: [PATCH 4/7] sched: Remove rq->cpu_load[]
Date: Mon, 27 May 2019 07:21:13 +0100	[thread overview]
Message-ID: <20190527062116.11512-5-dietmar.eggemann@arm.com> (raw)
In-Reply-To: <20190527062116.11512-1-dietmar.eggemann@arm.com>

The per rq load array values also disappear from the cpu#X sections in
/proc/sched_debug.
