Subject: [PATCH nf-next 0/4] netfilter: reduce hook sizes in struct net
Date: Mon, 13 Nov 2017 17:41:03 +0100 [thread overview]
Message-ID: <20171113164107.11259-1-fw@strlen.de> (raw)
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.
