And that someone should be in the From: address, and he gets the credit when it goes right, and blame when it gets wrong. Pick that person. He is responsible for reviewing mails the bot sends (perhaps adding information that would normally be there but syzbot is not yet able to add it automatically -- such as what tree it is to the subject), and he should act on replies. > > > and we also need to tell syzbot about the fix with: > > > > > > #syz fix: > > > userfaultfd: clear the vma->vm_userfaultfd_ctx if UFFD_EVENT_FORK fails > > > > Now you claimed you care about bugs being fixed.

Umm. Really? That's not how it historically worked. You report a bug, you are expected to care enough to do the testing. You also say a "thank you" to person who fixes the bug. Just because. And syzbot does not do any of that, and that's why human should be in the loop.
