And Ted, I don't think you realize just how at my limit I am here with
what I'm willing to put up with.

I'm coming off of, what, 6+ months of getting roasted and having my work
quested by Linus every pull request (and he did stop that, but not
before it had done real damage, both completely changing the tone of
public conversations and nearly scaring off people I've been trying to
hire).

It's gotten harder and harder, not easier, for me to get work done in
other parts of the kernel; I gave up long ago in the block layer after
the two people in charge there had repeatedly introduced silent data
corruption bugs into core block layer code that I'd written, without
CCing me, which I then had to debug, which they then ignored or put up
ridiculous fights over when reported, and now have turned petty on
subsequent block layer patches.

Filesystem people have been good to work with, thank god, but now
getting anything done in mm is looking like more and more of what the
block layer has turned into.

And you guys, because the system works for you, keep saying "nah,
everything is fine and this has already been decided, you don't get any
say".

Meanwhile, I'm seeing more and more heisenbugs in the rest of the kernel
as I'm stabilizing bcachefs, and my users are reporting the same - in
compaction, in the block layer, now in the scheduler or locking, I'm not
sure on the last one.

And I'm sitting here wondering how the hell I'm supposed to debug my own
code when I don't even have a stable base to work on anymore.

This is turning into an utter farce.
