Still entirely pointless.

If you have more than 4 billion inodes, something is really really wrong.

So why is it ten lines instead of one?

Dammit, this is a number that NOBODY HAS SHOWN IS EVEN WORTH EXISTING
IN THE FIRST PLACE.

So no. I'm not taking this. End of discussion. My point stands: I want
this filesystem *stabilized*, and in s sane format.

Look to *simplify* things. Send me patches that *remove* complexity,
not add new complexity that you have zero evidence is worth it.

Face it, eventfs isn't some kind of "real filesystem". It shouldn't
even attempt to look like one.

If somebody goes "I want to tar this thiing up", you should laugh in
their face and call them names, not say "sure, let me whip up a
50-line patch to make this fragile thing even more complex".
