Developers are asked to state that they are allowed to submit their

code using a Linux-kernel style "Signed-off-by:" line.

Quoting linux/Documentation/SubmittingPatches:

The sign-off is a simple line at the end of the explanation for the

patch, which certifies that you wrote it or otherwise have the right to

pass it on as an open-source patch. The rules are pretty simple: if you

can certify the below:

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
