Please read Documentation/process/submitting-patches.rst.
Search for "Signed-off-by:".

Most relevant:

Any further SoBs (Signed-off-by:'s) following the author's SoB are from
people handling and transporting the patch, but were not involved in its
development. SoB chains should reflect the **real** route a patch took
as it was propagated to the maintainers and ultimately to Linus, with
the first SoB entry signalling primary authorship of a single author.

and

The Signed-off-by: tag indicates that the signer was involved in the
development of the patch, or that he/she was in the patch's delivery path.


and lastly, gmail has (apparently) munged the whitespace in the patch
so that it is awful... or it was never done correctly if gmail didn't
munge it.
