I simply don't get the point of this series.

MDEV is an interface for exposing parts of a device to a userspace
program / VM. But that this series appears to do is to expose a
purely software defined nvme controller to userspace. Which in
principle is a good idea, but we have a much better framework for that,
which is called vhost.
