Making (literally) millions of devices in the field hit a WARN_ON() is
not really acceptable either though.

You can argue that this introduced a regression, but putting the old
behaviour back would equally be a regression, for more systems by a few
orders of magnitude.

In any case, I've already suggested a way to fix this, but you've both
completely ignored that part of my email. All I've been reading is that
you're demanding that I fix this, and arguments about how much people
are allowed to shoot themselves in the foot, none of which is very
constructive.

I might even fix it myself eventually, if only to appease the people
who say we have a zero tolerance no regressions rule, but it's not
exactly the most important thing I'm doing right now (also, I'll be
going on vacation for a few days, and you can probably implement my
suggestion in that time, and then I can review it when I get back on
Monday.)

Let's just say that I think we're discussing the wrong thing here - we
ought to be discussing how it can be fixed, and perhaps you can even be
constructive in suggesting (and testing, which I can't really do)
changes.
