You use access(2)

This is more challenging, and is a harder problem than I think we're
trying to solve in the short term.  Right now we're just looking for
an infrastructure to allow the file systems to keep track of process
authentication groups for multiple filesystems that want to use them.

How you actually push the authentication credentials into the kernel
is a separate problem, and I'm not sure if there *IS* a generic mechanism
for this (nor am I convinced there should or can be).

Let's solve the easier problem first, and then we can worry about the
harder problem.

What "common" auth structure do you mean?
