From 317e49b4aaa71aa4e96817e035083db7f1b964f0 Mon Sep 17 00:00:00 2001 From: Monam Agarwal Date: Thu, 27 Mar 2014 20:12:22 -0700 Subject: [PATCH] datapath: Use with RCU_INIT_POINTER(x, NULL) in vport-gre.c This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL) The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structure. And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by: Monam Agarwal Signed-off-by: Jesse Gross --- datapath/vport-gre.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/datapath/vport-gre.c b/datapath/vport-gre.c index 86137565a..5ba5b8e44 100644 --- a/datapath/vport-gre.c +++ b/datapath/vport-gre.c @@ -257,7 +257,7 @@ static void gre_tnl_destroy(struct vport *vport) ovs_net = net_generic(net, ovs_net_id); - rcu_assign_pointer(ovs_net->vport_net.gre_vport, NULL); + RCU_INIT_POINTER(ovs_net->vport_net.gre_vport, NULL); ovs_vport_deferred_free(vport); gre_exit(); } -- 2.47.0
