Subject: [PATCH v4 1/8] sched, fair: use __schedstat_set() in set_next_entity()
Date: Sun, 5 Sep 2021 14:35:40 +0000 [thread overview]
Message-ID: <20210905143547.4668-2-laoar.shao@gmail.com> (raw)
In-Reply-To: <20210905143547.4668-1-laoar.shao@gmail.com>
schedstat_enabled() has been already checked, so we can use
__schedstat_set() directly.
