------------------ From: Eric Dumazet <[email protected]> [ Upstream commit 71d9f6149cac8fc6646adfb2a6f3b0de6ddd23f6 ] br_multicast_query_expired() querier argument is a pointer to a struct bridge_mcast_querier : struct bridge_mcast_querier { struct br_ip addr; struct net_bridge_port __rcu *port; }; Intent of the code was to clear port field, not the pointer to querier.
