Subject: [PATCH net-next 0/2] ipv6: mc_forwarding changes

From: Eric Dumazet <edumazet@...gle.com>

First patch removes minor data-races, as mc_forwarding can
be locklessly read in fast path.

Second patch adds a short cut in ip6mr_sk_done()

Eric Dumazet (2):
  ipv6: make mc_forwarding atomic
  ip6mr: ip6mr_sk_done() can exit early in common cases
