This small series prepares for upcoming merge of the per-namespace hash tables into a single table (or rater, three tables -- conntrack hash, expect hash and nat bysrc hash). Arguments for merging it: - We stop wasting (assuming default size) 250k backing store per namespace - net namespace is just another part of the connection id, much like ip addresses or conntrack zones -- no need to treat it specially - allows to get rid of the per-netns conntrack slab as well These patches are first preparations. We replace per-netns conntrack has generation seqcount by single one. While at it, this replaces the method used to obtain the hash seed by the (nowadays) more common get_random_once(). -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
