Hi, This v2 drops a patch from v1 and fixes the chunk_sectprs check added to blk_stack_limits to convert chubk_sectors to bytes before comparing with physical_block_size. Jens, please feel free to pick up patches 1 and 2. DM patches 3 and 4 are provided just to give context for how DM will be updated to use chunk_sectors. Mike Snitzer (4): 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: unconditionally call blk_queue_split() in dm_process_bio() block/blk-settings.c | 22 ++++++++++++---------- drivers/md/dm-table.c | 5 +++++ drivers/md/dm.c | 45 +-------------------------------------------- include/linux/blkdev.h | 12 +++++++++--- 4 files changed, 27 insertions(+), 57 deletions(-) -- 2.15.0
