I'm not unalterably opposed to the idea, but I don't currently see a way
to do that without resolving block devices (struct gendisk) by name, and
that seems to be a no-no.

So a name like "sda1" is not viable? Why? What about "MAJOR:MINOR"?

I confess that I am not very familiar with internal blkdev API.

Quick look reveals that there is a struct block_device, containing a
member bd_disk, which is a pointer to struct gendisk.

What is the relationship between these two? Can there be a block device
without a gendisk, for example?
