Subject: [PATCH 2/6] sched, fair: use __schedstat_set() in set_next_entity()
Date: Tue, 1 Dec 2020 19:54:12 +0800 [thread overview]
Message-ID: <20201201115416.26515-3-laoar.shao@gmail.com> (raw)
In-Reply-To: <20201201115416.26515-1-laoar.shao@gmail.com>
schedstat_enabled() has been already checked, so we can use
__schedstat_set() directly.
