No, I will use the same hlist_node pointer (skc_bind_node) which was there, and skc_node and skc_node are removed. After all - we can traverse over the whole tree one-by one, it is even possible to attach a bitmask to each level node (since it is an array) of used/free entries and use it. -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
