BTW (to reply to two mails with one): Toke, thx for giving it a shot!

I know, I know... :-( Nevertheless thx for the reminder. :-D

I really wish that I had some, but right now the data I have in regzbot
is too messy and not a good base to generate such stats, as they would
likely be misleading (that's the long story short).

I once had the rough plan to approach this differently by looking at all
commits that ended up in the first big batches of stable updates (e.g.
releases like 6.0.3 with many hundreds of changes). I wanted to filter
out the regression fixes and then (1)look how long it took from posting
the fix till it was mainlined and (2)backported to stable. But there
afaics is no good way to automate the first part of the job: filtering
out fixes for regressions that actually bothered someone and might or
might not have been tracked by regzbot (the "might not" share might be
the bigger one, which is part of the valid stats problem indicated above).

Out of curiosity (really, it's not meant as a rhetorical device, I'm
trying to understand this point of view):

Why do you think that? And should it really be like that?

Sure, if it was an old problem (say from 5.18) that was only recently
found I'd agree, especially if the fix might have a more than average
risk of causing other trouble. But shouldn't we care about regressions
that were found shortly after a release (e.g. 6.2 in this case) at least
as much (or maybe even more?) as we care about those found during the
weeks preceding it?

FWIW, it's not the first time I hear a statement like that and every
time I wonder how Linus thinks about this. But whatever, not going to CC
him for that.

Ciao, Thorsten
