From e5fc3161969b3c82c8c61af8c8d360e39977ae2e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 30 Jan 2008 13:32:17 +0100 Subject: [PATCH] arch/x86/ia32: use time_before, time_before_eq, etc. 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/) // @ 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 @ no_include depends on !include && change_compare_np @ @@ #include + #include // [ mingo@elte.hu: merge to x86.git ] Signed-off-by: Julia Lawall Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- arch/x86/ia32/ia32_aout.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/arch/x86/ia32/ia32_aout.c b/arch/x86/ia32/ia32_aout.c index f1a0f83676dc..e4c12079171b 100644 --- a/arch/x86/ia32/ia32_aout.c +++ b/arch/x86/ia32/ia32_aout.c @@ -25,6 +25,7 @@ #include #include #include +#include #include #include @@ -359,13 +360,14 @@ static int load_aout_binary(struct linux_binprm *bprm, struct pt_regs *regs) #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.
