Since Stan is the original author of this and following patches, there should be a s-o-b tag from him. After that you should add yours indicating that you are carrying the patches from Stan.
Also, please add a cover letter stating the purpose of this series, how it is tested, and with any other relevant information.
Thanks,
Mani
