No as said before the parts for which we don't have a Signed-off-by
for falls under b), since we took it from existing code which has clear
GPLv2+ license headers on each and every file.

b) Reads:

        (b) The contribution is based upon previous work that, to the best
            of my knowledge, is covered under an appropriate open source
            license and I have the right under that license to submit that
            work with modifications, whether created in whole or in part
            by me, under the same open source license (unless I am
            permitted to submit under a different license), as indicated
            in the file; or

Right, and we do since the files we're basing our work on is GPLv2+ licensed,
the purpose of the listing of extra names other then the Signed-off-by:
tags is for solely for attribution.

Right but these are not Signed-off-by lines. Just as I may thank a tester
in a commit message with just his name because he does not want me to disclose
his email address, we are attributing people here with just there names.

Note in some cases we do have email addresses and Ian has said he will add those
in the next version, but we cannot magically conjure up Signed-off-by's which we
don't have, and section b) says we don't need to since all the original files
have a clear GPLv2+ license header.
