Dmitry, I wonder if there's a way to have syzbot know about what it's
testing and be able to run the pending patches for that tree? I think
we're up to 4 reports now that are all just fallout from the same bug,
and where a patch has been queued up for a few days. Since they all look
different, I can't fault syzbot for thinking they are different, even if
they have the same root cause.

Any way we can make this situation better? I can't keep replying that we
should test the current branch, and it'd be a shame to have a ton of
dupes.
