Thanks Jeremy! I should have an answer for you on Monday morning.

You know, I was trying to manufacture a way to do this with DMAPI (which
is
supported on JFS2) and set an event on {postcreate, postdelete,
postrename}
and check the errno value for success, but there seems to be absolutely
no
way to get the lib to do signalling. It appears to be a poll/select API.
Bummer....I wish IBM would put some of these cool Linux-only goodies in
their FS.
Cheers,
Bill

I have tested this patch (Samba 3.0.22 + Jeremy's patch) and everything
seems to be solid and it solves my problem.
I'll be putting it into production later this week.
Thank you very much,
Claus
