All three are in mainline; none carried Cc: stable, so they were not auto-selected for 6.12.y. Per your earlier reply, resending as a three-patch series: https://lore.kernel.org/all/20260610-stable-reply-0014@kernel.org/ d5059e52 is already in the v6.18.y and v7.0.y stable trees: https://github.com/gregkh/linux/commit/91e77840bf13de3add125060cf8b32ca24a52c8c https://github.com/gregkh/linux/commit/35180c772f5e11e2fa4d80d3dfd50906cb6d9646 The three must go together. 5ed54896 adds mt7921_roc_abort_sync() on the sta-remove path, which runs under dev->mt76.mutex (taken by mt76_sta_remove()); d5059e52 then turns cancel_work_sync() inside roc_abort_sync() into cancel_work() to avoid a self-deadlock with roc_work(). Applying 5ed54896 alone queues a reachable deadlock. 6.12.y note: d5059e52 keeps del_timer_sync() -- the timer_delete_sync() rename is not in 6.12.y. The other two cherry-pick cleanly. Tested on MT7921e: Acer Aspire 5 A517-52, ASUS VivoBook S14, Lenovo IdeaPad Slim 5 14AHP9. Link to v2: https://lore.kernel.org/all/20260617130826.1667503-1-rauty@altlinux.org/ v3: * subject prefix now carries target branch (6.12.y) * cover letter added with stable backport status of d5059e52 * no code changes
