I understood you cannot certify that you have the rights to send the
patch. Adding someone's else Signed-off-by does not solve the problem
of lack of such permission. Marek could certify that but you cannot
certify for him. Otherwise it really makes the process bogus - anyone
can add Linus' SoB and say that Linus certified the rights to include
this contribution.

In my understanding of Developer's Certificate of Origin 1.1, these
patches do not meet the criteria and therefore should not be included
from that point of view.

One minor comment further.

Unfortunately there was no mails coming from Sangbeom Kim so I think
he is not active in maintaining these pieces. Let's skip this entry.

Best regards,
