I'd not submit something with known glaring issues, so whether it's
the fixed #4 (intermdiary or whatever), or #5, at least make sure it's
as clean as possible.  I'd also make sure that locking is correct, and
that you've cared for refcounting things properly in the case of umount,
for example (IOW, look out for the things that inotify got wrong).

Perhaps one thing that would help is a succinct explanation of why
inotify is insufficient, because with dnotify being marginal functional
yet merged, inotify being worked on and this, all overlapping, the
obvious questions will be around consolidating work.  In fact, something
that clearly states the requirements would be a good starting point.

Sorry I haven't had much time to review this lately ;-(
