Hello SJ,

Thanks for reviewing both patches!

I used b73198a47ffe in Fixes because that commit introduced the problem
with the temporal tuner.

I thought a Fixes tag could also point to a commit that is still in a
maintainer tree. The tip handbook describes that for tip [1], though mm
may handle it differently.

The hash can still change in mm-unstable, so the tag may need updating.

I also found this reply from Andrew [2]. He says he tracks these fixes
by filename and folds them into the original patch before moving it to
non-rebasing git.

Maybe squashing is indeed simpler here, also for backports.

So either option is fine with me. I'll leave that to you and Andrew.
