IMO, OOM can recover it certainly but with much cost, so we should avoid the case. I don't think NAPI can avoid it, because NAPI will cause skb to be allocated without any limit if there are packets coming, still no chance left for usbnet_bh to handle and free these SKBs. thanks, -- Ming Lei -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
