Date: Mon, 24 Dec 2007 15:45:32 +0100 (CET) From: Julia Lawall <julia@...u.dk> To: shemminger@...ux-foundation.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH 30/38] net/bridge: Use time_before, time_before_eq, etc. From: Julia Lawall <julia@...u.dk> The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. A simplified version of the semantic patch making this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @ change_compare_np @ expression E; @@ ( - jiffies <= E + time_before_eq(jiffies,E) | - jiffies >= E + time_after_eq(jiffies,E) | - jiffies < E + time_before(jiffies,E) | - jiffies > E + time_after(jiffies,E) ) @ include depends on change_compare_np @ @@ #include <linux/jiffies.h> @ no_include depends on !include && change_compare_np @ @@ #include <linux/...> + #include <linux/jiffies.h> // </smpl> Signed-off-by: Julia Lawall <julia@...u.dk> --- diff -r -u -p a/net/bridge/br_netfilter.c b/net/bridge/br_netfilter.c --- a/net/bridge/br_netfilter.c 2007-11-15 15:09:37.000000000 +0100 +++ b/net/bridge/br_netfilter.c 2007-12-23 20:30:40.000000000 +0100 @@ -46,6 +46,7 @@ #include "br_private.h" #ifdef CONFIG_SYSCTL #include <linux/sysctl.h> +#include <linux/jiffies.h> #endif #define skb_origaddr(skb) (((struct bridge_skb_cb *) \ @@ -221,7 +222,7 @@ static void __br_dnat_complain(void) { static unsigned long last_complaint; - if (jiffies - last_complaint >= 5 * HZ) { + if (time_before_eq(jiffies, last_complaint + 5 * HZ)) { printk(KERN_WARNING "Performing cross-bridge DNAT requires IP " "forwarding to be enabled\n"); last_complaint = jiffies; -- 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/
