Ooops... Sorry. I messed up the cover letter. Here are the changes:

Damien Le Moal (16):

  scsi: sd_zbc: Rearrange code

  scsi: sd_zbc: Use well defined macros

  scsi: sd_zbc: Fix sd_zbc_read_zoned_characteristics()

  block: Add zoned block device information to request queue

  scsi: sd_zbc: Initialize device request queue zoned data

  scsi: sd_zbc: Limit zone write locking to sequential zones

  scsi: sd_zbc: Disable zone write locking with scsi-mq

  block: mq-deadline: Add zoned block device data

  block: mq-deadline: Introduce zones_wlock attribute

  blokc: mq-deadline: Introduce dispatch helpers
