    dm - adjust use of minor numbers to new reality
    
    * Allocate (theoretical) minor numbers using the devfs_clone_bitmap
      facility instead of an ever-increasing int64.
    
    * Set the actual minor of the dm-specific device information to the
      minor returned by the disk subsystem.
    
    * Undo some of the dkunit() uses as they only covered very specific use
      cases.
