So this patch isn't actually needed, I thought the fsnotify_open() call
was deeper than it is.  I'm going to drop this particular patch.

Can I take silence on the list as a lack of disagreement?  I'd like to
start putting these into linux-next starting tomorrow.  Obviously I'd
like to see the networking definitions approved and taken by davem, I'd
like to see the FMODE_ change approved and taken by viro, but if you two
would like me to push it directly I'd be happy to.

Davem, maybe you'd rather my af_fanotify was somewhere inside net/
instead of in fs/notify/fanotify?  I'd love to get some review here, but
noone onlist is excited enough to step up.  (I have numerous people who
have privately claimed they intend to use this stuff, so i promise it
won't be dead code.)

I'm ready to start committing and adding features, anyone telling me no?

-Eric
