Subject: [PATCH] mm/damon/sysfs: use the wrapper directly to check if the kdamond is running
Date: Mon, 12 Sep 2022 23:11:53 +0800 [thread overview]
Message-ID: <1662995513-24489-1-git-send-email-kaixuxia@tencent.com> (raw)
From: Kaixu Xia <kaixuxia@tencent.com>
We can use the 'damon_sysfs_kdamond_running()' wrapper directly to
check if the kdamond is running in 'damon_sysfs_turn_damon_on()'.
