You're still not getting it.

The "didn't go far enough" means that the bug fix is *BUGGY*. It needs
to be reverted.

But that very must *IS* the answer. If there isn't a fix for the ABI
breakage, then the first bugfix needs to be reverted.

Really. There is no such thing as "but the fix was more important than
the bug it introduced".

This is why we started with the whole "actively revert things that
introduce regressions". Because people always kept claiming that "but
but I fixed a worse bug, and it's better to fix the worse bug even if
it then introduces another problem, because the other problem is
lesser".

NO.

We're better off making *no* progress, than making "unsteady progress".

Really. Seriously.

If you cannot fix a bug without introducing another one, don't do it.
Don't do kernel development.

The whole mentality you show is NOT ACCEPTABLE.

So the *only* answer is: "fix the bug _and_ keep the API". There is
no other choice.

The whole "I fixed one problem but introduced another" is not how we
work. You should damn well know that. There are no excuses.

And yes, sometimes that means jumping through hoops. But that's what
it takes to keep users happy.
