Andrea, thank you for this series. I ran the new test cases and they work as
expected. They all failed with the kernel v7.3, and they all passed with the
kernel fix patch series.

Overall, the patches in this series look good to me. I made some comments for
further improvement. Please check and see if they make sense for you.
