Thanks Nic,
applied to the configfs-for-next tree. I'm not entirely sure if we
should bother adding this to 4.12 or if it hits rarely enough?
It hits for us pretty often when we have a GPFS setup with 10 hosts and 1k+ vms.
That is how we discovered the bug in the first place.

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

Patch 2 and 3 introduce support for host managed zoned blo
ore using it, and
also to be more readable we adjust the bidi code.

tcmu: Support emulate_write_cache
tcmu: Add netlink for device
This gives tcmu the ability to handle events that can cause
reconfiguration, such as resize, path changes, write_cache, etc...

For write_pending if the queue is down or client failed
then return -EIO so that LIO can properly process the
completed command. Prior we returned 0 since LIO could
