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? Marek
