Subject:    [Ocfs2-devel] [PATCH 6/6] ocfs2: don't use write_one_page in ocfs2_duplicate_clusters_by_page

[Download RAW message or body]

Use filemap_write_and_wait_range to write back the range of the dirty
page instead of write_one_page in preparation of removing write_one_page
and eventually ->writepage.
