The upcoming NVMe ZNS Specification will define a new type of write
command for zoned block devices, zone append.

When when writing to a zoned block device using zone append, the start
sector of the write is pointing at the start LBA of the zone to write to.
Upon completion the block device will respond with the position the data
has been placed in the zone. This from a high level perspective can be
seen like a file system's block allocator, where the user writes to a
file and the file-system takes care of the data placement on the device.

Applied to 5.8/scsi-queue, thanks!

Btw any other comments on the SCSI parts of this series or the general 
architecture from your side Martin?
