We could allow only one process to open /dev/parportx at a time.
If you like to have more than one ppuser process that schedule the same
parport I think it' s better define something like:
dev name minor
This isn' t malleable but it' s a rock solid (maybe a bit too much ;-)
I have not thought about this a lot (nor I have read the code), it' s only
an idea and I could be wrong.
BTW, we just know that minor numbers are only 256, but with 2.3 I hope
somebody will change the ext2 inode to handle 64bit of minor and major
numbers (to get rid of other problems too). There is also devfs that would
_workaround_ the problem.

Are the dentries unique?
