Hi Hannes, I went over all of your patches and made a few tweaks, comments, and improvements along the way. Patch headers were modified very slightly. I wasn't seeing the need for (m->queue_io << 1) + m->queue_if_no_path in v5's "[PATCH 3/6] dm-multipath: push back requests instead of queueing" so I simplified that and documented the change in the header. If there is a reason for what you had please explain. Patch 7 offers and incremental cleanup that builds on your v5 patchset. I can rebase/modify any aspect of these patches so please just let me know if there is something that needs changing. Jun'ichi, I didn't add any tag for your contributions to this patchset (either Acked-by or Reviewed-by) but I'd like you to reply to this v6 patchset with those if you're OK with these changes. Thanks, Mike Hannes Reinecke (5): dm mpath: do not call pg_init when it is already running dm mpath: push back requests instead of queueing dm mpath: remove process_queued_ios() dm mpath: reduce memory pressure when requeuing dm mpath: remove map_io() Mike Snitzer (2): dm table: add dm_table_run_md_queue_async dm mpath: remove extra nesting in map function when path exists drivers/md/dm-mpath.c | 208 ++++++++++++++---------------------------- drivers/md/dm-table.c | 19 ++++ drivers/md/dm.c | 5 + drivers/md/dm.h | 1 + include/linux/device-mapper.h | 5 + 5 files changed, 100 insertions(+), 138 deletions(-) -- 1.8.1.4 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
