No you didn;t but we need to do this properly.
Assuming you're suggesting to implement that, I can't say I'm excited by
the idea of reworking a non trivial chunk of block layer to fix a problem
and then porting it up to some 5.x, especially since it was already
attempted before by someone and ultimately got reverted.
Stop whining. Backporting does not matter for upstream development,
and I'm pretty sure you'd qualify for a job where you don't have to do
this if you actually care and don't just like to complain.
That's an interesting choice of words. Dear Christoph, I'm afraid you
don't realise that you're the one whining at a person who actually tries
to fix it. I'd appreciate if you stop this bullshit, especially if you're
not willing to fix it yourself. If you do, please, be my guest and prove
me wrong.
Stable does exist, and people do care about it, and people do care about
problems being fixed and not delayed because your desire for someone else
to do some random grand rework for you. If there are _actual_ problems
with the patch, please let me know. Some of more rare cases being not
as efficient is not a problem.
