This is useful at times when multiple people work on a single patch. Note, this person also needs to have a Signed-off-by: line in the patch as well. """ So it is not wrong to have two Signed-off-bys, just that having the Co-Developed-by tag clearly shows that there was more than one author. Without the Co-Developed-by tag, the second Signed-off-by tag is ambiguous, since the seconds Signed-off-by tag might just have meant that that person was in the delivery chain of the patch. I think that the Co-Developed-by tag is optional, so if the co-developer doesn't care about taking credit, it can probably be skipped. Kind regards, Niklas
