[PATCH net-next 00/10] net: add data-race annotations around dst fields

[Eric Dumazet <edumazet@google.com>]

Add annotations around various dst fields, which can change under us.

Add four helpers to prepare better dst->dev protection,
and start using them. More to come later.

Eric Dumazet (10):
  net: dst: annotate data-races around dst->obsolete
  net: dst: annotate data-races around dst->expires
  net: dst: annotate data-races around dst->lastuse
  net: dst: annotate data-races around dst->input
  net: dst: annotate data-races around dst->output
  net: dst: add four helpers to annotate data-races around dst->dev
  ipv4: adopt dst_dev, skb_dst_dev and skb_dst_dev_net[_rcu]
  ipv6: adopt dst_dev() helper
  ipv6: adopt skb_dst_dev() and skb_dst_dev_net[_rcu]() helpers
  ipv6: ip6_mc_input() and ip6_mr_input() cleanups
