Subject: Re: [PATCH 0/3] Add support for Block Passthrough Endpoint function
 driver

Please don't just create a new (and as far as I can tell underspecified)
new "hardware" interface for this.  If the nvme endpoint work is too
much for your use case maybe just implement a minimal virtio_blk
interface.
