The second patch depends on the first, so I kept the upstream ordering instead of folding either change into the other. The first patch is already present in 6.6.y. The 6.6.y backport of the second patch is queued (6.6.158-rc1). Both patches are already present in 6.12.y, 6.18.y, and 7.2.y. Could you please queue this series for 6.1.y? AI assistance: An LLM helped identify, adapt, and validate these backports; I reviewed the resulting code and validation evidence. Thanks, Artem Dinaburg Series: 1. bpf: Fail bpf_timer_cancel when callback is being cancelled 2. bpf: Defer work in bpf_timer_cancel_and_free
