Message

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.

  block: introduce zone_write_granularity limit
  block: document zone_append_max_bytes attribute
