It came from the kernel Documentation/process/submitting-patches.rst,
which doesn't have that specific text about "verbatim copies". I guess
you prefer we copy it from https://developercertificate.org/?

I do see that Eclipse had it on a page with other content. Although,
the main focus of the page is the DCO.
https://www.eclipse.org/legal/DCO.php

It doesn't look like https://developercertificate.org/ has a filename
associated with the content. So, something like docs/dco.txt or
docs/developer-certificate-of-origin.txt?
