Hello, this patch queue converts gfs2 to use iomap for buffered writes, which uses multi-page block allocations for large writes instead of a separate allocation for each page of data. Apply on top of the current gfs2 for-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2.git/log/?h=for-next Changes since v1: * Add write_begin and write_end iomap operations instead of the minimal iomap_written operation from the prevous patch queue. These operations need to be wired up by filesystems that implement writes over iomap. * Several bug fixes in the gfs2 specific patches. This patch queue doesn't convert direct I/O, so we still have a remaining user of the old gfs2_write_begin / gfs2_write_end interface left. Once direct I/O is converted to iomap, we'll get rid of some more old code.
