This should not be a problem. Even though they are called minor numbers,
they must not be confused with the device minor numbers which are shown
in /dev. These are always the same as the inode number of the device.

The minor numbers which are currently being used inside the kernel have
no actual purpose, but are only there to remain compatible with certain
KPI's.
