Tried to post this to python-dev, but that seems to have gone who-knows-where:
I’m in the process of bringing the mock backport up to date, but this has got me stumped:
$ git log --oneline --no-merges 5943ea76d529f9ea18c73a61e10c6f53bdcc864f… – Lib/unittest/mock.py Lib/unittest/test/testmock/ | tail

Right, so I’ve merged up to 15f44ab043, what comes next?
$ git log --oneline --no-merges 15f44ab043… – Lib/unittest/mock.py Lib/unittest/test/testmock/ | tail -n 3
161a4dd495 Issue #28919: Simplify _copy_func_details() in unittest.mock

Okay, no idea why 0be894b2f6 is there, appears to be a totally identical commit to 15f44ab043, so let’s skip it:
$ git log --oneline --no-merges 0be894b2f6… – Lib/unittest/mock.py Lib/unittest/test/testmock/ | tail -n 3

Wat?! Why is 15f44ab043 showing up again?!
What’s the git subtlety I’m missing here?
