The authorship of each patch in a series

The authorship of each patch in a series

[Fabio M. De Francesco]

Hi all,

Another developer and I collaborated to design and write a series of four 
patches. Of course, we will both use the "Co-developed-by" and "Signed-off-
by" tags on each of the four works that make up the series.

However, there is a small problem that we would like to solve. Git-log only 
displays a single name preceded by "Author:", so the reader of "git log --
pretty = short" will only be shown one of our names.

We would like git-log to show one name after "Author:" in 1/4 and 4/4 and the 
other name in 2/4 and 3/4. This arbitrary breakdown is based on the fact that 
approximately 80% -90% of the lines of code from the first patch group were 
actually written by one of the two co-developers and approximately 80% -90% 
of the second patch group was written by the other.

I guess Git will label anyone who submits the whole series as "Author"; works 
like this or am I wrong? If so, I guess if my friend sends patches 0/4, 1/4 
and 4/4 then I should find a way to send 2/4 and 3/4 somehow that makes it 
clear to the maintainer, the tool that uses to apply the series, and the 
reviewers, which also 2/4 and 3/4 belong to the same series as 0/4, 1/4 and 
4/4.

How can we achieve this?

Thanks,

Fabio

Commit the patches to your local tree with the correct authorship
information (some from you, some from them), and then when you create
the patch series, the correct names will show up in the email as who
authored them as the "From:" line.

Try it locally and see, this happens all the time in kernel development.

As an example, see all of the stable-kernel -rc release announcements
with the patches in them.  The original authorship is preserved just
fine.

thanks,

greg k-h

Thank you very much, we will use your suggestion to send that series for  
staging-test as soon as it is fully refined and properly tested.

Fabio
