Subject: [PATCH nf-next v2 00/11] netfilter: reduce struct net size
Date: Thu,  1 Apr 2021 16:11:03 +0200	[thread overview]
Message-ID: <20210401141114.24712-1-fw@strlen.de> (raw)

This series moves part of netfilter related pernet data from
struct net to net_generic() infrastructure.

All of these users can be modules, so if they are not loaded there
is no need to waste space.

Also, none of the struct members that are (re)moved are used in packet
path.

A followup patch series will also remove ebt/arp/ip/ip6tables xt_table
anchors from struct net.

Size reduction is 7 cachelines on x86_64.

Only change since v1 is in patch 7, it removes a 'unused variable'
warning.

Florian Westphal (11):
  netfilter: nfnetlink: add and use nfnetlink_broadcast
  netfilter: nfnetlink: use net_generic infra
  netfilter: cttimeout: use net_generic infra
  netfilter: nf_defrag_ipv6: use net_generic infra
  netfilter: nf_defrag_ipv4: use net_generic infra
  netfilter: ebtables: use net_generic infra
  netfilter: nf_tables: use net_generic infra for transaction data
  netfilter: x_tables: move known table lists to net_generic infra
  netfilter: conntrack: move sysctl pointer to net_generic infra
  netfilter: conntrack: move ecache dwork to net_generic infra
  net: remove obsolete members from struct net
