If we are going to stick to ENOENT for page that wasn't faulted in the kernel from now on we should stick to it in the test as well. Also I think there is a third case that we do not cover either, what happens when we pass an address that is not mapped at all, e.g. NULL? Do we get EFAULT as well? -- Cyril Hrubis chrubis@xxxxxxx
