Subject: [PATCH 3/3] f2fs: fix to check f2fs_compressed_file() in f2fs_bmap()
Date: Fri, 27 Mar 2020 18:29:53 +0800 [thread overview]
Message-ID: <20200327102953.104035-3-yuchao0@huawei.com> (raw)
In-Reply-To: <20200327102953.104035-1-yuchao0@huawei.com>
Otherwise, for compressed inode, returned physical block address
may be wrong.
