    [PATCH] remove protection of LANANA-reserved majors
    
    Revert all this.  It can cause device-mapper to receive a different major 
from
    earlier kernels and it turns out that the Amanda backup program (via GNU 
tar,
    apparently) checks major numbers on files when performing incremental 
backups.
    
    Which is a bit broken of Amanda (or tar), but this feature isn't important
    enough to justify the churn.
