Has this been tested? If anyone is interested in testing these patches with the Ubuntu distro, I created a 5.15.39 based test kernel which is packaged as a .deb. This test kernel has the rt-42 patch set, and the four patches from David. This test kernel can be downloaded from: https://people.canonical.com/~jsalisbury/MEMCG_UNSUPPORTED_TEST_KERNEL/ This kernel will also be tested in an Ubuntu kernel bug[0].  The bug reporter will be testing if the patches resolve a bug that affects kubernetes, which is missing cgroup memory.  However, the bug reporter will probably not be testing latency differences.  That is something I could look into next week.
