Yes.

Yeah, I noticed that after I posted it.

I was at the end of my self-imposed, "I'm only giving myself 3 hours for
this", and didn't want to touch it anymore :)

Yeah, I originally tried a different function from namei.c, but getting
the mount point was a bit messy at the moment.

I'll take some time later this week and fix this up and post it one more
time for anyone else to use.

But remember, I'll be posting it, and not asking for it to be accepted,
as I was wrong.  devfs is not needed, it's wrong, and will be removed
from the kernel.  But more about that later...

thanks,
