-If you are a subsystem or branch maintainer, sometimes you need to slightly
-modify patches you receive in order to merge them, because the code is not
-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
-enclosed in square brackets, is noticeable enough to make it obvious that
-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>
-
-This practise is particularly helpful if you maintain a stable branch and
-want at the same time to credit the author, track changes, merge the fix,
-and protect the submitter from complaints. Note that under no circumstances
-can you change the author's identity (the From header), as it is the one
-which appears in the changelog.
-
-Special note to back-porters: It seems to be a common and useful practise
-to insert an indication of the origin of a patch at the top of the commit
-message (just after the subject line) to facilitate tracking. For instance,
-here's what we see in 2.6-stable :
-
