Re: [PATCH 0/5] target: Zoned block device support and bug fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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.
