Message-Id: <1395600379-9668-1-git-send-email-monamagarwal123@gmail.com> Date: Mon, 24 Mar 2014 00:16:19 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: eparis@...hat.com, linux-kernel@...r.kernel.org Subject: [PATCH] kernel: Use RCU_INIT_POINTER(x, NULL) in audit.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 <monamagarwal123@...il.com> --- kernel/audit.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/audit.c b/kernel/audit.c index 3392d3e..bc240ba 100644 --- a/kernel/audit.c +++ b/kernel/audit.c @@ -1087,7 +1087,7 @@ static void __net_exit audit_net_exit(struct net *net) audit_sock = NULL; } - rcu_assign_pointer(aunet->nlsk, NULL); + RCU_INIT_POINTER(aunet->nlsk, NULL); synchronize_net(); netlink_kernel_release(sock); } -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
