Subject: [PATCH 1/4] f2fs: clean up codes with {f2fs_,}data_blkaddr()
Date:   Fri, 14 Feb 2020 17:44:10 +0800
Message-ID: <20200214094413.12784-1-yuchao0@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

- rename datablock_addr() to data_blkaddr().
- wrap data_blkaddr() with f2fs_data_blkaddr() to clean up
parameters.
