This fixes minor data-races in ip6_mc_input() and batadv_mcast_mla_rtr_flags_softif_get_ipv6()
Signed-off-by: Eric Dumazet edumazet@google.com Signed-off-by: David S. Miller davem@davemloft.net --- net-next commit 145c7a793838 ("ipv6: make mc_forwarding atomic")
This still needs compat code - does anyone have ideas?
