From: Julia Lawall <julia@xxxxxxx> 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@xxxxxxx> --- diff -r -u -p a/arch/sparc64/kernel/binfmt_aout32.c b/arch/sparc64/kernel/binfmt_aout32.c --- a/arch/sparc64/kernel/binfmt_aout32.c 2007-10-22 11:24:59.000000000 +0200 +++ b/arch/sparc64/kernel/binfmt_aout32.c 2007-12-23 20:33:56.000000000 +0100 @@ -27,6 +27,7 @@ #include <linux/binfmts.h> #include <linux/personality.h> #include <linux/init.h> +#include <linux/jiffies.h> #include <asm/system.h> #include <asm/uaccess.h> @@ -273,7 +274,8 @@ static int load_aout32_binary(struct lin } else { static unsigned long error_time; if ((ex.a_text & 0xfff || ex.a_data & 0xfff) && - (N_MAGIC(ex) != NMAGIC) && (jiffies-error_time) > 5*HZ) + (N_MAGIC(ex) != NMAGIC) && + time_after(jiffies, error_time + 5*HZ)) { printk(KERN_NOTICE "executable not page aligned\n"); error_time = jiffies; diff -r -u -p a/arch/sparc64/kernel/unaligned.c b/arch/sparc64/kernel/unaligned.c --- a/arch/sparc64/kernel/unaligned.c 2007-06-02 22:32:07.000000000 +0200 +++ b/arch/sparc64/kernel/unaligned.c 2007-12-23 20:30:39.000000000 +0100 @@ -20,6 +20,7 @@ #include <linux/smp.h> #include <linux/bitops.h> #include <linux/kallsyms.h> +#include <linux/jiffies.h> #include <asm/fpumacro.h> /* #define DEBUG_MNA */ @@ -283,7 +284,7 @@ static void log_unaligned(struct pt_regs { static unsigned long count, last_time; - if (jiffies - last_time > 5 * HZ) + if (time_after(jiffies, last_time + 5 * HZ)) count = 0; if (count < 5) { last_time = jiffies; - To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
