Well, we're poking at the queue (for block size) and the bdi. I guess we
could split things up and have another function to twiddle these
parameters separately. During revalidate, perhaps.

But the fundamental question remains: Why is it a prerequisite for the
NVMe integrity profile to be added before the disk is live? Nobody else
requires this (sd, md, dm).
