I am thinking of how to make this automagic and useful for me. My plan
is (and ymmv):

When I write a patch, have a git hook generate  "Message-Id" in my
patch changelog itself when it is written using Greg/Andrew's
make_message_id. This Message-Id is not the final message-id and is
just for reference purposes for later processing. Then when sending
it, after git format-patch I will do a few things:
  (a) Consult the archive to check the highest value of N for which
Message-Id-<N> does not exist
  (b) Add Message-Id: Message-Id-<N> to the patch header so git
send-email uses this as the Message-Id-<N>
  (c) Add this Message-Id-<N> as a Link: to the changelog;  Possibly
removing Message-Id<N-1> link.
  (d) Remove the original "Message-Id" without the -<N> from the
changelog since it has no purpose.
  (e) Send the patch

This will automatically link all the previous revisions of a patch
vN..vN-1...v1...0.  And also does not need any manual labor - which is
one of the main selling points AIUI of Google's git hooks for using
"Change-Id:".  Also works for Doug's use case and for people wanting
to have a Link: tag.

Such a git hook can then be provided to the kernel community to better
automate their flow of Link: generation. Although the steps (a) to (e)
may require additional tooling and changing of the local git tree at
the time a patch is submitted - which is Ok for my flow but not sure
if it would work for everyone.

Thoughts?

thanks,

- Joel
