I agree to disagree :-)

Which is pretty useless, since it doesn't apply to any recent
(> 2.4.3) kernel. If you insist on a xattr based approach, take
Andy Lutomirski's <http://www.stanford.edu/~luto/linux-fscap/>
patch. It is more recent, a lot smaller and considerably more
understandable (at least for me ;-).
