Forgive me if this has already been discussed, or is explained deeper in the patch series... The commit message sounds like you're extending virtio-blk to optionally emulate zoned storage. Correct? PATCH 1 adds a new block block device driver 'zoned_host_device', and PATCH 9 exposes it in QAPI. This is for passing through a zoned host device, correct?
