Date: Mon, 24 Mar 2014 00:45:59 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: linville@...driver.com, johannes@...solutions.net, davem@...emloft.net, linux-wireless@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] net/mac80211: Use RCU_INIT_POINTER(x, NULL) in debugfs.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/mac80211/debugfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/mac80211/debugfs.c b/net/mac80211/debugfs.c index fa16e54..0e963bc 100644 --- a/net/mac80211/debugfs.c +++ b/net/mac80211/debugfs.c @@ -128,7 +128,7 @@ static ssize_t sta_tx_latency_stat_write(struct file *file, if (!strcmp(buf, TX_LATENCY_DISABLED)) { if (!tx_latency) goto unlock; - rcu_assign_pointer(local->tx_latency, NULL); + RCU_INIT_POINTER(local->tx_latency, NULL); synchronize_rcu(); kfree(tx_latency); goto unlock; -- 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
