That's unlikely, since again this will be unused by the all but iscsi users. But you can be tricky and replace skb destructor with your own pointer and call 'old' destructor yourself. Its main goal is to adjust socket memory statistics and since all iscsi sockets are under your full control, you can play with it. Although this sounds like a hack, with proper implementation it is not that bad idea. As additional pointer you can use sk_user_data which is used by rpc socket calls only iirc. -- Evgeniy Polyakov -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
