See [2] for a recommend reading on writing commit messages.
+Your patches should also include a Signed-off-by line with your name and
+email address. If you're not the patch's original author, you should
+also gather S-o-b's by them (and/or whomever gave the patch to you.) The
+significance of this is that it certifies that you created the patch,
+that it was created under an appropriate open source license, or
+provided to you under those terms. This lets us indicate a chain of
+responsibility for the copyright status of the code.
+
+We won't reject patches that lack S-o-b, but it is strongly recommended.
