The patches up to this one look good. (I didn't reply for each
individual one to avoid unnecessarily sending messages to the list.)
About this patch: will lazily initializing these fields be done in a
later patch?

This doesn't seem up-to-date - they are being replaced with a function
call, not a field access. I would be OK with just removing this "Patch
generated by" section.

Here (and elsewhere), "the_repository->objects.packed_git" instead of
"get_packed_git" is still used.
