So pretty much one branch per patch? Really? How am I going to keep
track of all of that?
Ok, even with a few "topic" branches if we can group them by subsystem
is going to be really tough, let's look at the 3.4.4-rc1 kernel as an
example. At first guess, that looks like it would have at least 25
different branches. I'm all for "octopus" merges, but isn't that a bit

Please write the scripts to do so then, right now, the work it takes me
to do the stable releases is not much at all, as I've scripted it pretty
well. For me to change how that works would require a bunch of rework
of both my scripts, and my workflow, for almost no-gain that I can see.
Actually, it looks like more work, as I'm sure I will get those topic
