Message-ID: <20080307030901.GA4375@darkstar.te-china.tietoenator.com> Date: Fri, 7 Mar 2008 11:09:01 +0800 From: Dave Young <hidave.darkstar@...il.com> To: linux-kernel@...r.kernel.org Cc: akpm@...ux-foundation.org Subject: [PATCH RFC] add time_after_now and other macros which compare with jiffies Most of time_after like macros users just compare jiffies and another number, so here add some other _now macros to do it. Another aproach is changing original time_ macros to use jiffies to compare, add a generic compare macro like time_compare(a, b) Signed-off-by: Dave Young <hidave.darkstar@...il.com> --- jiffies.h | 8 ++++++++ 1 file changed, 8 insertions(+) diff -upr linux/include/linux/jiffies.h linux.new/include/linux/jiffies.h --- linux/include/linux/jiffies.h 2008-03-07 10:40:04.000000000 +0800 +++ linux.new/include/linux/jiffies.h 2008-03-07 10:50:12.000000000 +0800 @@ -134,6 +134,14 @@ static inline u64 get_jiffies_64(void) ((__s64)(a) - (__s64)(b) >= 0)) #define time_before_eq64(a,b) time_after_eq64(b,a) +#define time_after_now(a) time_after(jiffies, a) + +#define time_before_now(a) time_before(jiffies, a) + +#define time_after_eq_now(a) time_after_eq(jiffies, a) + +#define time_before_eq_now(a) time_before_eq(jiffies, a) + /* * Have the 32 bit jiffies value wrap 5 minutes after boot * so jiffies wrap bugs show up earlier. -- 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/
