The first patch in this series introduces the zone write granularity queue limit to indicate the alignment constraint for write operations into sequential zones of zoned block devices. The second patch fixes adds the missing documentation for zone_append_max_bytes to the sysfs block documentation. The third patch switch zonefs to use this new limit as the file block size instead of using the physical block size. Changes from v2: * Added patch 3 for zonefs * Addressed Christoph's comments on patch 1 and added the limit initialization for zoned nullblk Changes from v1: * Fixed typo in patch 2 Damien Le Moal (3): block: introduce zone_write_granularity limit block: document zone_append_max_bytes attribute zonefs: use zone write granularity as block size Documentation/block/queue-sysfs.rst | 13 ++++++++++ block/blk-settings.c | 39 +++++++++++++++++++++++++---- block/blk-sysfs.c | 8 ++++++ drivers/block/null_blk/zoned.c | 1 + drivers/nvme/host/zns.c | 1 + drivers/scsi/sd_zbc.c | 10 ++++++++ fs/zonefs/super.c | 9 +++---- include/linux/blkdev.h | 15 +++++++++++ 8 files changed, 86 insertions(+), 10 deletions(-) -- 2.29.2
