Documentation/SubmittinPatches defines the semantics of SoB as: < ------------ snip snap snop ----------- > Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. then you just add a line saying Signed-off-by: Random J Developer <random@xxxxxxxxxxxxxxxxxxxxx> < ------------ snip snap snop ----------- > I'm normally accept non-trivial patches with just a single SoB line though I might ask for the original author(s)' SoB in some cases or might just complain missing SoBs and apply a patch anyway if it's trivial which means like 10 lines of not quite rocket science content.
