• HOTtoday [PATCH v5 0/3] can_rx_offload keeps a lockless irq_queue that the IRQ handlers fill and that is later spliced under skb_queue.lock into the NAPI-facing skb_queue. This works as long as a single context fills the irq_queue. flexcan with FLEXCAN_QUIRK_SECONDARY_MB_IRQ and mcf5441x use two mailbox IRQ lines. When those are affined to different CPUs the two handlers can enqueue into the same list at the same time and corrupt it.
