From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Snitzer Subject: [PATCH v3 0/6] dm: fix then improve bio splitting Date: Mon, 21 Sep 2020 22:32:45 -0400 Message-ID: <20200922023251.47712-1-snitzer@redhat.com> Return-path: Sender: Mike Snitzer To: Jens Axboe Cc: Ming Lei , Vijayendra Suman , dm-devel@redhat.com, linux-block@vger.kernel.org List-Id: dm-devel.ids Hi, Patches 1 and 2 are queued for me to send to Linus later this week. Patches 3 and 4 are block core and should get picked up for 5.10. Jens, please pick them up. I revised the header for patch 4 to give better context for use-case where non power-of-2 chunk_sectors occurs. Patch 4 enables DM to switch to using blk_max_size_offset() in Patch 6. Patches 5 and 6 just show how DM will be enhanced for 5.10 once patches 3 and 4 land in the block tree. Mike Snitzer (6): dm: fix bio splitting and its bio completion order for regular IO dm: fix comment in dm_process_bio() block: use lcm_not_zero() when stacking chunk_sectors block: allow 'chunk_sectors' to be non-power-of-2 dm table: stack 'chunk_sectors' limit to account for target-specific splitting dm: change max_io_len() to use blk_max_size_offset() block/blk-settings.c | 22 ++++++++++++---------- drivers/md/dm-table.c | 5 +++++ drivers/md/dm.c | 47 +++++++++++++---------------------------------- include/linux/blkdev.h | 12 +++++++++--- 4 files changed, 39 insertions(+), 47 deletions(-) -- 2.15.0
