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?
