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.
