From 4f2479f03c06e29d7d9e1e02191f8b5ba8ad4eef Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 30 Jan 2008 13:32:18 +0100 Subject: arch/x86/kernel/apm_32.c: use time_before, time_before_eq, 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 // Signed-off-by: Julia Lawall Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- arch/x86/kernel/apm_32.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'arch/x86/kernel/apm_32.c') diff --git a/arch/x86/kernel/apm_32.c b/arch/x86/kernel/apm_32.c index e32f6c37db9b..2467df7eca0b 100644 --- a/arch/x86/kernel/apm_32.c +++ b/arch/x86/kernel/apm_32.c @@ -227,6 +227,7 @@ #include #include #include +#include #include #include @@ -1287,7 +1288,7 @@ static void check_events(void) "event 0x%02x\n", event); } if (ignore_bounce - && ((jiffies - last_resume) > bounce_interval)) + && (time_after(jiffies, last_resume + bounce_interval))) ignore_bounce = 0; switch (event) { -- cgit v1.2.3
