Maybe something like this? speed = do_div(BENCH_SIZE, 1024) * count * do_div(NSEC_PER_SEC, ns_end); This might not be exactly right because it changes the operator precedence, but it should eliminate the calls to __udivdi3. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
