For this virtio_input patch: theoretical for stable. On the failing path, virtio_device_ready() has run, but virtinput_fill_evt() has not, so the event queue still has no buffers. I have no evidence of device DMA into torn-down queues here; the change is lifecycle hygiene matching remove/freeze (clear DRIVER_OK before del_vqs()). I will drop Cc: stable on a v2 and keep the fix for mainline only. I will answer the same question separately on the virtio_pci and virtio_mmio threads. Thanks, Xiong
