Got it, but I could need some advice on it if you have a minute.

Does that report really look like a regression from your point of view?
The part "The code has been this way in the kernel for a very long time,
which suggests that it has been working, [...]" sounds like it is, but
OTOH it's quite vague.

I'm asking, because with my regression tracking work and regzbot I focus
on regressions and ignore things that were always broken, as I (at least
for now) don't want it to become yet another bug tracker (and I guess I
would quickly drown in bugs as well).

But if you think this case looks like a regression, I'll add it. Guess I
just need to be creative then how to tell regzbot when it got
introduced. Guess I'll settle on v2.6.13..v5.15", that should indicate
there is something strange here. It's a use-case I hadn't expected. But
well, that's why I wanted to something for testing. :-D

Ciao, Thorsten
