Sorry for bothering. I have no experience with backport things so I need some
more guidance here.

The fix patch needs two of the cleanup patches applied. I currently have no idea
what I could do to make backport easier. Should I also add "Fixes:" tag to the
two cleanup patch? Or should I squash the two cleanup and one fix together to
make a patch just for backport?
