Please go back to customer and ask them "why", then let us know. Could I suggest you stop working on implementation things and instead work on preparing a comprehensive bug report? Describe the workload, describe the system behavior, describe why it is problematic, describe the preferred behavior, etc. Once we have that understanding, it might be that we eventually agree that the problem is unfixable using existing memory management techniques and that it is indeed appropriate that we add a lot more code which essentially duplicates kswapd functionality and which essentially duplicates direct reclaim functionality. But I sure hope not.
