Not to pick on you too much but the initial history looked pretty messy
to me - a lot of layering violations - it made aio.c look clean.

I know you were in "get shit done" mode, but at some point we have to
take a step back and ask "what are the different core concepts being
expressed here, and can we start picking them apart?". A generic
ringbuffer would be a good place to start.

I'd also really like to see some more standardized mechanisms for "I'm a
kernel thread doing work on behalf of some other user thread" - this
comes up elsewhere, I'm talking with David Howells right now about
fsconfig which is another place it is or will be coming up.

good tests, code coverage analysis to verify, good syzbot coverage?
