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.
Thanks,
Andreas
