Date: Thu, 29 Dec 2022 06:10:30 -1000

filemap_fdatawrite_wbc is a fairly thing wrapper around do_writepages, and
the big difference there is support for cgroup writeback, which is not
supported by ocfs2, and the potential to use ->writepages instead of
->writepage, which ocfs2 does not currently implement but eventually
should.
