We haven't had that before, I don't see why it's suddenly such a big deal.

The notification side I understand. Polling /proc files is not the answer.

But the whole "let's design this crazy subsystem for it" seems way
overkill. I don't see anybody caring that deeply.

It really smells like "do it because we can, not because we must".

Who the hell cares about monitoring mounts at a kHz frequencies? If
this is for MIS use, you want a nice GUI and not wasting CPU time
polling.

I'm starting to ignore the pull requests from David Howells, because
by now they have had the same pattern for a couple of years now:
esoteric new interfaces that seem overdesigned for corner-cases that
I'm not seeing people clamoring for.

I need (a) proof this is actualyl something real users care about and
(b) way more open discussion and implementation from multiple parties.

Because right now it looks like a small in-cabal of a couple of people
who have wild ideas but I'm not seeing the wider use of it.

Convince me otherwise. AGAIN. This is the exact same issue I had with
the notification queues that I really wanted actual use-cases for, and
feedback from actual outside users.

I really think this is engineering for its own sake, rather than
responding to actual user concerns.
