We're solving some cross-over between this series and Vlastimil's set of fixes from anthropic: https://lore.kernel.org/linux-mm/20261027-pgalloc-ai-hotfixes-v1-0-9c7d1aca801e@kernel.org/ Have discussed with Vlastimil, and i'm going to pull patches 4/9 and 5/9 from his series onto this series when i respin this for his updates. That should keep the backport issues self-contained on this series. -- ~Gregory
