It would do it, but that's completely useless to mlock() an entire application just for this reason. copy_from_user() and copy_to_user() are specifically designed to handle page faults that may occur during the copy. They allow the page of the user application to be retrived from the backing store transparently. Just as if the page was accessed by the application itself.
