Could somebody explain how the following situation is supposed to be handled: 1) branch B1 with commits C1, C2, C3, C4 is pushed out 2) C2 turns out to have a bug, which gets caught and fixed 3) fix is folded in and branch B2 with C1, C2', C3', C4' is pushed out. The bug is not in it anymore. 4) B1 is left mouldering (or is entirely removed); B2 is eventually merged into other trees. This is normal and it appears to be problematic for syzbot. How to deal with that? One thing I will *NOT* do in such situations is giving up on folding the fixes in. Bisection hazards alone make that a bad idea.
