+Subject: [PATCH] genetlink: hold RCU in genlmsg_mcast()
+
+[ Upstream commit 56440d7ec28d60f8da3bfa09062b3368ff9b16db ]
+
+While running net selftests with CONFIG_PROVE_RCU_LIST=y I saw
+one lockdep splat [1].
+
+genlmsg_mcast() uses for_each_net_rcu(), and must therefore hold RCU.
+
+Instead of letting all callers guard genlmsg_multicast_allns()
+with a rcu_read_lock()/rcu_read_unlock() pair, do it in genlmsg_mcast().
+
+This also means the @flags parameter is useless, we need to always use
+GFP_ATOMIC.
