That doesn't mean that *You* can add a Signed-off-by: Nobody can certify sign-off for anybody else. Read the sign-off rules: you can add your *own* sign-off if the rules hold, but you can't sign off for somebody else. The "Co-developed-by: must be immediately followed by a Signed-off-by:" thing only means that if there are multiple developers, then ALL DEVELOPERS MUST SIGN OFF. It absolutely does *NOT* mean that you adding a Co-developed-by means that you then add a Signed-off-by. That's like faking somebody else's signature on some paperwork. Never do that either, and it's hopefully obvious why. Linus
