Sign-off in Linux kernel project is to certify that you have the right to contribute the change to the project under Developers certificate of origin. I believe in thier project, the document in Documentation/process/submitting-patches.rst describes the process (look for "Sign your work")

The "commit -s" signing has nothing to do with it. It may prove it was written by the key holder, but it does not prevent the key holder to steal intellectual property from their employer and contribute it as if it is their own, and Sign-off exists as a separate procedure to have you raise your right hand and swear that your contribution is kosher wrt DCO.
