Allow users to manually tell bisection range when automatic bisection found a wrong commit.
Also, allow users to specify reproducer program when automatic bisection found a wrong commit.
Yes, this is anti automation. But since automation can't become perfect, I'm suggesting manual adjustment. Even if we involve manual adjustment, the syzbot's plenty CPU resources for building/testing kernels is highly appreciated (compared to doing manual bisection by building/testing kernels on personal PC environments).

syzbot currently cannot test kernels with custom patches (unless "#syz test:" requests). Are you saying that syzbot will become be able to test kernels with custom patches?
