The tip handbook describes that for tip [1], though mm > may handle it differently. You could do use a commit hash that is still in a maintainer tree. I also sometimes do so. But in the case it is better to explicitly mention it is for squashing on mm-unstable. And if it was the intention, in this patch series, you were better to split the kunit patch. > > The hash can still change in mm-unstable, so the tag may need updating. > > I also found this reply from Andrew [2].

I'll leave that to you and Andrew. Thank you for clarifying, Karl. I was initially tempted to keep what I did (option 2), but maybe that's only because I am too lazy. Let's do squash. Unless others raise other opinion, I will repost patch 1 with updated commit message tomorrow. I will keep patch 2 in damon/next and repost for mm.git merge as I explained in the earlier reply. Thanks, SJ [...]
