Subject: [PATCH] sysv: delete unnecessary checks before brelse()
Date: Fri, 19 Aug 2022 08:13:20 +0000 [thread overview]
Message-ID: <20220819081320.96141-1-chi.minghao@zte.com.cn> (raw)
From: Minghao Chi <chi.minghao@zte.com.cn>
The brelse() function tests whether its argument is NULL
and then returns immediately.
Thus remove the tests which are not needed around the shown calls.
