Subject: [Ocfs2-devel] [PATCH] ocfs2: Remove repeated uptodate check for buffer
Date: Sun, 25 Apr 2021 10:57:02 +0800 [thread overview]
Message-ID: <20210425025702.13628-1-wanjiabing@vivo.com> (raw)
In commit 60f91826ca62 ("buffer: Avoid setting buffer bits that are
already set"), function set_buffer_##name was added a test_bit() to
check buffer, which is the same as function buffer_##name.
The !buffer_uptodate(bh) here is a repeated check. Remove it.
