struct net contains: struct nf_hook_entries __rcu *hooks[NFPROTO_NUMPROTO][NF_MAX_HOOKS]; which store the hook entry point locations for the various protocol families and the hooks. This can be compacted a lot by only storing the families and hooks that are actually implemented. struct net before: /* size: 5184, cachelines: 81, members: 46 */ after: /* size: 4544, cachelines: 71, members: 46 */ In case this is too late just ignore this thing, I will resubmit once next opens again. -- 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
