Subject: [PATCH 3/7] sched/debug: Remove sd->*_idx range on sysctl
Date: Mon, 27 May 2019 07:21:12 +0100 [thread overview]
Message-ID: <20190527062116.11512-4-dietmar.eggemann@arm.com> (raw)
In-Reply-To: <20190527062116.11512-1-dietmar.eggemann@arm.com>
This reverts commit 201c373e8e48 ("sched/debug: Limit sd->*_idx range on
sysctl").
Load indexes (sd->*_idx) are no longer needed without rq->cpu_load[].
The range check for load indexes can be removed as well. Get rid of it
before the rq->cpu_load[] since it uses CPU_LOAD_IDX_MAX.
At the same time, fix the following coding style issues detected by
scripts/checkpatch.pl:
ERROR: space prohibited before that ','
ERROR: space prohibited before that close parenthesis ')'
