One of Herbert's patches has: Reported-by: syzbot+56c7151cad94eec37c521f0e47d2eee53f9361c4@xxxxxxxxxxxxxxxxxxxxxxxxx ... so syzbot will close this bug report once this patch is applied and reaches upstream or linux-next. It's just a coincidence that syzbot happened to report a bisection result now. - Eric
