From mboxrd@z Thu Jan 1 00:00:00 1970 From: Monam Agarwal Subject: [PATCH] drivers/net: Use RCU_INIT_POINTER(x, NULL) in bonding/bond_options.c Date: Mon, 24 Mar 2014 00:00:17 +0530 Message-ID: <1395599417-7041-1-git-send-email-monamagarwal123@gmail.com> To: fubar@us.ibm.com, vfalico@redhat.com, andy@greyhouse.net, netdev@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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 --- drivers/net/bonding/bond_options.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/bonding/bond_options.c b/drivers/net/bonding/bond_options.c index 6e6b093..724e30f 100644 --- a/drivers/net/bonding/bond_options.c +++ b/drivers/net/bonding/bond_options.c @@ -712,7 +712,7 @@ static int bond_option_active_slave_set(struct bonding *bond, /* check to see if we are clearing active */ if (!slave_dev) { pr_info("%s: Clearing current active slave\n", bond->dev->name); - rcu_assign_pointer(bond->curr_active_slave, NULL); + RCU_INIT_POINTER(bond->curr_active_slave, NULL); bond_select_active_slave(bond); } else { struct slave *old_active = bond->curr_active_slave; -- 1.7.9.5
