-exactly the same in your tree and the submitters'. If you stick strictly to
-rule (c), you should ask the submitter to rediff, but this is a totally
-counter-productive waste of time and energy. Rule (b) allows you to adjust
-the code, but then it is very impolite to change one submitter's code and
-make him endorse your bugs. To solve this problem, it is recommended that
-you add a line between the last Signed-off-by header and yours, indicating
-the nature of your changes. While there is nothing mandatory about this, it
-seems like prepending the description with your mail and/or name, all

-you are responsible for last-minute changes. Example :
-
-	Signed-off-by: Random J Developer <random@developer.example.org>
-	[lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
-	Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
