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, in this straight from the jetplane edition I present the series to convert gfs2 to full iomap usage for the ordered and writeback mode, that is we use iomap_page everywhere and entirely get rid of buffer_heads in the data path. This has only seen basic testing which ensured neither 4k or 1k blocksize in ordered mode regressed vs the xfstests baseline, although that baseline tends to look pretty bleak. The series is to be applied on top of my "lift the xfs writepage code into iomap v2" series.
