Gotcha. I can keep it out from the regular patch flow. How could we
address commits that might have been missed? Let's say I look at commits
that are older than ~1 month, how can I get those looked at again?

I think we're just hitting the limitations of using a mailing list. Bots
aren't around to spam everyone for fun, right?

0day bot is spammy because patches fail to compile, syzbot is spammy
because we have tons of bugs users can hit and the stable bot is
spammy because we miss lots of commits that should be in stable.

As the kernel grows, not only the codebase is expanding but also the
tooling around it. While spammy, bots provide valuable input that in the
past would take blood, sweat and tears to acquire. We just need a better
way to consume it rather than blocking off these inputs.

Thanks!
