Hello everyone It's been a few months since I started sending patches, but there are still some points about the process that I do not quite understand. I would be really grateful if anyone could help clarify them for me. 1) How do we credit more than one person as an author? Here at the University of São Paulo we sometimes develop patches in pair programming, and I don't really know if in these cases we should just add the S-o-B of both authors or add the "Co-Developed-by" tag (or something else). Also, is this something specific to each subsystem? 2) Does iio have a test infrastructure? I know there are autobuilders playing with the iio.git testing branch, but how does it work? Also, if there is no test beyond building, is there some plan to make such an infrastructure in the near future? 3) When a reviewer sends an Acked-by, but I still have to send a v2 for some reason (maybe adjusting the patch message, e.g.), should I add the Acked-by in v2 or that's something the maintainers will do? Thank you Matheus
