dash marker line as described in Documentation/SubmittingPatches to
temporarily embed that information into the patch that you send.
+Q: Are all networking bug fixes backported to all stable releases?
+
+A: Due to capacity, Dave could only take care of the backports for the last
+ 2 stable releases. For earlier stable releases, each stable branch maintainer
+ is supposed to take care of them. If you find any patch is missing from an
+ earlier stable branch, please notify stable@vger.kernel.org with either a
+ commit ID or a formal patch backported, and CC Dave and other relevant
+ networking developers.
+
Q: Someone said that the comment style and coding convention is different
for the networking content. Is this true?
