Yeah, a lot of CIs that grep for certain keywords in the kernel log
(or that simply enable the panicking) suffer from those, but the idea
I was mentioning is to defer that until the fuzzing starts -- see
Ted's reply, it sounds potentially doable.

It may not solve the complete problem, but it may allow you, for
certain trees or periods of time, to continue your testing. Thus
removing a bit of the coupling between you and other maintainers, i.e.
making life easier for both sides.

I don't know -- I am just trying to find compromises that could help you.

Cheers,
Miguel
