Yap, just stick those rules somewhere on a website.
Btw, this is not only useful for a follow-on, fix patch but also for
initial test request. For example, I want to backport patch to stable
and would like to run it on a bunch of kernels:
base-commit: v4.4-stable, v4.9-stable, ...
i.e., a list of trees to apply it to. I believe people might like this a
Or, for example, a patch touching a bunch of arches and author doesn't
necessarily have access to all those different toolchains. Shoot a mail
to the 0day bot:
arch: x86_64, powerpc, sparc, ...
Would be very useful too.
Anyway, just a couple of ideas.
What would also be cool if you guys had a 0day bot howto with all those
things we should pay attention to and we can go and look up.
