Subject: [PATCH] f2fs: trival cleanup in move_data_block()
Date:   Wed, 30 Dec 2020 16:38:35 +0800
Message-ID: <20201230083835.115049-1-yuchao0@huawei.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

Trival cleanups:
- relocate set_summary() before its use
- relocate "allocate block address" to correct place
- remove unneeded f2fs_wait_on_page_writeback()
