As I expected, inside that repo are a lot of tags for the various -rt

First I thought, RT would make use of rebasing, like:
  - Rebase onto the next kernel version and drop unnecessary commits
(e.g. patches that went upstream)
  - Do some additional changes
  - Export vA.B.C...vA.B.C-rtX as split quilt queue

But afaict, (at least on the old rt-history), you made a lot of merges
from rt/* branches and added tags describing the -rt version. Then you
went on merging against master in order to keep up with upstream.

Given that, how do you create a split quilt queue, that applies against
an upstream tag?

For example, let's take the first RT Tag of rt-history: v2.6.31-rc6-rt2
How would you create a split quilt queue, that applies against v2.6.31-rc6?

(I need to extract all those split quilt queues RT version<->base
upstream version)

As I said before: That was an experiment whether git is usable as a tool to
manage something complex as rt. It turned out, that it's not. I recreated a
new quilt queue after I abondoned git for rt.

So creating split queues is going to be a very interesting and tedious
detective work.
