Merge patch series "scsi: scsi_debug: fix zoned write validation"

Niklas Cassel <cassel@kernel.org> says:

This series fixes scsi_debug with regards to writes to a ZBC drive, and to
WRITE ATOMIC (16). Each patch describes the problem that it fixes.

Two configurations are refused rather than emulated, and those two patches
come first, as the rest of the series relies on what they exclude: a zoned
device whose lowest aligned LBA is not zero, which no host writing in units
of the reported zone write granularity could ever write, and atomic writes
on a zoned device, which no drive supports.

Little of this is reachable in a default configuration. Most of it needs
physblk_exp, atomic_wr or logical block provisioning to be set, or an
initiator that does not provide a data buffer matching the transfer length
of the command.

The series is based on 7.4/scsi-staging rather than 7.3/scsi-fixes (as
Damien suggested on v1) to avoid a build failure that would have happened
if this series was simply merged with linux-next:

  error: too many arguments to function 'mk_sense_buffer'

Tested on a zoned scsi_debug device with 512 byte logical blocks and a 4096
byte physical block, and on a device that is not zoned for the WRITE ATOMIC
(16) patches. The notes below each patch describe what was observed before
and after it.
