Sorry I wasn't clear: I'm saying *replace*, not add,
I don't understand what you are proposing then. There are some instances that do want to know how many bytes did make it before the -EFAULT event.
You have to add a new version of the interface to handle both the case that cares about the length copied successfully and the case that only cares about -EFAULT vs. !-EFAULT - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
