Glad to see the seed added. In NVMe it can be a 64-bit value so we
should bump the size of that field in the user API.
Not sure what to do about the storage tag. For Linux that would probably
be owned by the filesystem (as opposed to the application). But I guess
one could envision a userland application acting as a storage target and
in that case the tag would need to be passed to the kernel.
