Eric Dumazet 9d159d6637 ipv6: mcast: remove one synchronize_net() barrier in ipv6_mc_down() ... [ Upstream commit 17ef8efc00b34918b966388b2af0993811895a8c ] As discussed in the past (commit 2d3916f318 ("ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()")) I think the synchronize_net() call in ipv6_mc_down() is not needed. Under load, synchronize_net() can last between 200 usec and 5 ms. KASAN seems to agree as well.
