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.
