Message-Id: <1395602620-15480-1-git-send-email-monamagarwal123@gmail.com> Date: Mon, 24 Mar 2014 00:53:40 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: johannes@...solutions.net, linville@...driver.com, davem@...emloft.net, linux-wireless@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] net/wireless: Use RCU_INIT_POINTER(x, NULL) in reg.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> --- net/wireless/reg.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/wireless/reg.c b/net/wireless/reg.c index 90b82e0..4dc08cc 100644 --- a/net/wireless/reg.c +++ b/net/wireless/reg.c @@ -2594,7 +2594,7 @@ void wiphy_regulatory_deregister(struct wiphy *wiphy) reg_num_devs_support_basehint--; rcu_free_regdom(get_wiphy_regdom(wiphy)); - rcu_assign_pointer(wiphy->regd, NULL); + RCU_INIT_POINTER(wiphy->regd, NULL); if (lr) request_wiphy = wiphy_idx_to_wiphy(lr->wiphy_idx); -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
