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/x86/ia32/ia32_aout.c b/arch/x86/ia32/ia32_aout.c --- a/arch/x86/ia32/ia32_aout.c 2007-10-22 11:25:00.000000000 +0200 +++ b/arch/x86/ia32/ia32_aout.c 2007-12-23 20:31:29.000000000 +0100 @@ -25,6 +25,7 @@ #include <linux/binfmts.h> #include <linux/personality.h> #include <linux/init.h> +#include <linux/jiffies.h> #include <asm/system.h> #include <asm/uaccess.h> @@ -344,14 +345,15 @@ static int load_aout_binary(struct linux #ifdef WARN_OLD static unsigned long error_time, error_time2; if ((ex.a_text & 0xfff || ex.a_data & 0xfff) && - (N_MAGIC(ex) != NMAGIC) && (jiffies-error_time2) > 5*HZ) + (N_MAGIC(ex) != NMAGIC) && + time_after(jiffies, error_time2 + 5*HZ)) { printk(KERN_NOTICE "executable not page aligned\n"); error_time2 = jiffies; } if ((fd_offset & ~PAGE_MASK) != 0 && - (jiffies-error_time) > 5*HZ) + time_after(jiffies, error_time + 5*HZ)) { printk(KERN_WARNING "fd_offset is not page aligned.
