I'm really worried about how this is tied into the sd driver.

the scheduler that is done through struct scsi_disk is the
offset + len -> zone number lookup - I'd much rather expose this
from sd upwards and keep the scheduler in the
This series implements support for ZBC disks used through the scsi-mq I/O path.
The current scsi level support of ZBC disks guarantees write request ordering
using a per-zone write lock which prevents issuing simultaneously multiple
write commands to a zone, doing so avoid reordering of sequential
