I do not think this apply to patches, and as a consequence to the RedHat kernel and more generally SRPMS and Debian source packages: the point of this requirement is to prevent a modified version to pass for the original version, but source packages provide the unmodified source tarball (so no file is actually modified, so the requirement is void) and some patches (which in any case include the lists of files which are modified) and even a changelog that list changes with the date.
