You aren't being pedantic, I think you are missing exactly what the
linux-stable-rc tree is for and how it is created.
Granted, it's not really documented anywhere so it's not your fault :)
The linux-stable-rc tree is there ONLY for people who want to test the
-rc kernels and can not, or do not want to, use the quilt tree of
patches in the stable-queue.git tree on kernel.org. I generate the
branches there from a script that throws away the current -rc branch and
rebuilds it "from scratch" by applying the patches that are in the
stable-quilt tree and then adds the -rc patch as well. This tree is
generated multiple times when I am working on the queues and then when I
want to do a "real" -rc release.
The branches are constantly rebased, so you can not rely on 'git pull'
doing the right thing (unless you add --rebase to it), and are there for
Yes, you will see different results of a "-rc1" release in the tree
depending on the time of day/week when I created the tree, and sometimes
I generate them multiple times a day just to have some of the
auto-builders give me results quickly (Linaro does pull from it and
sends me results within the hour usually).
So does that help? Ideally everyone would just use the quilt trees from
stable-queue.git, but no everyone likes that, so the -rc git tree is
there to make automated testing "easier". If that works with your
workflow, wonderful, feel free to use it. If not, then go with the
stable-quilt.git tree, or the tarballs on kernel.org.
And as for the SHA1 being in the emails, that doesn't make all that much
sense as that SHA1 doesn't live very long. When I create the trees
locally, I instantly delete them after pushing them to kernel.org so I
can't regenerate them or do anything with them.
DOes that help explain things better?
