I took a couple of different versions of the series for a spin, and for
me it stops working between these versions.

$ git fetch https://github.com/guoren83/linux.git generic_entry_v12:ge-v12
$ git fetch https://github.com/guoren83/linux.git generic_entry_v13:g2-v13

v12 is happy with systemd, v13 is not.
