See http://www.infradead.org/rpr.html Sender: linux-fsdevel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-fsdevel@vger.kernel.org Hi all, this series cleans up the xfs writepage code and then lifts it to fs/iomap.c so that it could be use by other file system. I've been wanting to this for a while so that I could eventually convert gfs2 over to it, but I never got to it. Now Damien has a new zonefs file system for semi-raw access to zoned block devices that would like to use the iomap code instead of reinventing it, so I finally had to do the work. Changes since v5: - move the tracing code to fs/iomap/trace.[ch] - fix a bisection issue with the tracing code - add an assert that xfs_end_io now only gets "complicated" completions - better document the iomap_writeback_ops methods in iomap.h Changes since v4: - rebased on top 5.4-rc1 - drop the addition of list_pop / list_pop_entry - re-split a few patches to better fit Darricks scheme of keeping the iomap additions separate from the XFS switchover Changes since v3: - re-split the pages to add new code to iomap and then switch xfs to it later (Darrick) Changes since v2: - rebased to v5.3-rc1 - folded in a few changes from the gfs2 enablement series Changes since v1: - rebased to the latest xfs for-next tree - keep the preallocated transactions for size updates - rename list_pop to list_pop_entry and related cleanups - better document the nofs context handling - document that the iomap tracepoints are not a stable API
