And since the FSF released the file it is based on under GPLv2+, if
you release your patch, presumably a copyrightable derived work, it
must be released under GPLv2 or, at your option, any later version.

If the patch is not a copyrightable work, discussing its copyright
license is like asking "how much wood would a woodchuck chuck if a
woodchuck would chuck wood?" :-)
