Hi Jan, This idea was suggested on year ago [1], but I never got to test its performance benefits. Following the performance improvement report from kernel robot [2], please consider these changes. I have other optimization patches for no ignored mask etc, but the "no marks" case is the most low hanging improvement. Thanks, Amir.
