See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-btrfs@vger.kernel.org btrfs_writepage_endio_finish_ordered is a small wrapper around btrfs_mark_ordered_io_finished that just changs the argument passing slightly, and adds a tracepoint. Move the tracpoint to btrfs_mark_ordered_io_finished, which means it now also covers the error handling in btrfs_cleanup_ordered_extent and switch all callers to just call btrfs_mark_ordered_io_finished directly.
