Because I blindly used the lists reported by scripts/get_maintainer.pl ...

I'll build a "mailing list <=> git tree" mapping based on MAINTAINERS
and use that to build CC list, rather than depending on the source files
that the patch randomly touch.

That's a valid option. Unfortunately I don't have a website to run
this for now. Anyway, I'm still on the way improving the kernel
testing backend based on your and others' feedback :)

That's where a website could help. Different kconfigs may trigger
different errors for the same commit. So it's a hard decision whether
to send emails for all broken kconfigs and risk being a noise, or to
limit it to the first broken kconfig and risk lose of information.

For now, I can send the patch author all the emails, but CC others
only on the first one (with an statement that there are actually more
errors in other kconfigs). So that the author that is responsive for
fixing the bug get the full information, while the others still can
keep track of the error situation.

Heh, thanks! We should be able to reach a polished automated system
that's fast and accurate in the end :-)
