That question is exactly the reason why my Nack stands. First, that's a BS reason for a NACK. But in all seriousness, what I would actually ask (and what I'll ask now) is, what module did you use that is out of tree, and was it relevant to this test? That's a reasonable question to ask, and one that only gets asked with a taint. If there's a BPF injection taint, one can ask that same question, as the bug may happen sometime after the injection but be caused by that injection, and not be in the backtrace. Not all kernel developers have the access to debugging utilities that backend production servers have. A lot of bugs that kernel developers debug are from someone's laptop. Where all they have is that backtrace. If a tool or root kit, added function error injection, it would be extremely useful information to debug what happened. I don't understand the push back here. -- Steve
