Signed-off-by: certifies that you wrote it or otherwise have the right to pass it on as a open-source patch. Specifically, that you agree to the Developer's Certificate of Origin

Acked-by: If a person was not directly involved in the preparation or handling of a patch but wishes to signify and record their approval of it then they can arrange to have an Acked-by: line. Acked-by: does not necessarily indicate acknowledgement of the entire patch.

Tested-by: A Tested-by: tag indicates that the patch has been successfully tested (in some environment) by the person named. This tag informs maintainers that some testing has been performed, provides a means to locate testers for future patches, and ensures credit for the testers.

Reviewed-by: A Reviewed-by tag is a statement of opinion that the patch is an appropriate modification without any remaining serious technical issues. Any interested reviewer (who has done the work) can offer a Reviewed-by tag for a patch.

Also we have **Co-developed-by:
