Re: [PATCH net] net/sched: taprio: unwind the netdevice notifier if register_qdisc() fails

[phx <phx0fer@gmail.com>]

Hi, The issue was found by LLM-assisted review of this code path (static analysis), not from a production hit or a syzbot report. I then wrote a reproducer and ran it on an arm64 QEMU guest under KASAN; it fired at the claimed sink (notifier_call_chain, vmalloc-out-of-bounds). The "Assisted-by: LLM" trailer reflects that assistance. Thanks.
