Oh well.. we'll see when I get to it. I have a few higher > priority things on my pile at the moment. I have no problems with that. I'd always intended to have flags go further up the call chain like Linus did (since we'd discussed perhaps making faults interruptible and requiring an extra flag to distinguish get_user_pages callers that were not interruptible). So yes adding more flags to improve code or make things simpler is fine by me :) Thanks, Nick -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
