This series introduce zoned block device support for the pscsi backstore and
also fixes several problems with sense data handling for failed requests.
The first patch is only a cleanup, so not really necessary but nice to have I
think.
Patch 2 and 3 introduce support for host managed zoned block device type (14h)
in the SCSI passthrough backstore and fixes sense data handling for commands
failed by the backstore device. With these fixes, a host zoned block device
exported with the iscsi or loopback transport pass libzbc ZBC specification
conformance tests.
Finally, patch 4 and 5 fix sense data hadling with the user backstore code. A
prototype ZBC emulation tcmu-runner handler was used to test these fixes and
result in the emulated handler passing libzbc ZBC specification conformance
tests.
(Note: the ZBC emulation tcmu-runner handler will be submitted to the
tcmu-runner project on github)
Please consider these patches for inclusion with kernel 4.13.

Hi Damien,
You should take a look at the first two patches in this series to address your
sense data handling.
