That sounds ok to me. I especially like adding the NTSTATUS
return :-).

FYI: We're going to need to be able to flag opens from
unix clients separately though so we will be able to do
unlink on open files and not have the share modes conflict
if all opens are unix style - similar to what I did with
the posix lock code. Just wanted to run that past you.
