I am more worried about timer latencies and its effects. Because of this skew between when jiffy interrupt was originally supposed to happen and when it will now happen, it can lead to, for example, scheduling latencies upto 1 jiffy (for HZ=100, that could hurt some apps?) Not to mention that this will not play well with high-res-timers, but that is probably not a concern now! -- Thanks and Regards, Srivatsa Vaddagiri, Linux Technology Center, IBM Software Labs, Bangalore, INDIA - 560017 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
