[Xen-devel] tags in backport commits

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

I think we should discuss and agree on a set of tags to use in our
backports to stable trees.

Specifically, I would like to see a tag that specifies the id of the
original commit, like "master commit" that Jan is using today. I would
prefer if the tag didn't have any spaces, thus, I suggest
master-commit-id or upstream-commit-id (that's what I use in the
qemu-xen trees because it wouldn't be clear what "master" is in that
context). Whatever is chosen should be documented under docs.

Moreover, I think we should start using tags in our staging commits
which specify to which trees a given commit should be backported to as
soon as it passes the push gate. I suggest to use something similar to
the Linux kernel:

  CC: stable@xxxxxxxxxxxxxx [4.2+]
or
  CC: stable@xxxxxxxxxxxxxx # 4.2+

But anything else that allows us to specify a range of stable trees
would be fine by me. This is the first step toward backport automation.
What do you think?

Cheers,

Stefano
