Subject: [PATCH] sched/fair: Trivial fix for comment of check_preempt_tick
Date: Sun, 17 Jan 2021 12:08:47 +0800 [thread overview]
Message-ID: <20210117040847.12217-1-benbjiang@tencent.com> (raw)
From: Jiang Biao <benbjiang@tencent.com>
check_preempt_tick() is not just for newly woken task preemption,
and check_preempt_wakeup() is instead.
The current comment of check_preempt_tick() is a little confusing.
