It requires work, and an AI generated request doesn't change the reality that *someone* has to do that work, I invite you to figure out a way to figure out an AI mediated tool that can attempt the backport, and then run the moral equivalent of "gce-xfstests -c ext4.all -g auto" to verify that the backport doesn't result in any regressions. (Some previous attempts to backport to older LTS kernels have resulted in the kernels crashing as a result.) Otherwise, I recommend that most users consider switching to a newer LTS kernel, or if they can't to pay $$$ to an enterprise Linux distribution that pays engineers to do that hard work. - Ted
