I was thinking about extending page pool for other mem providers and what came to mind was either optionally replacing the free / alloc with a function pointer: https://github.com/torvalds/linux/commit/578ebda5607781c0abb26c1feae7ec8b83840768 or wrapping the PP calls with static inlines which can direct to a different implementation completely (like zctap / io_uring zc). Former is better for huge pages, latter is better for IO mem (peer-to-peer DMA). I wonder if you have different use case which requires a different model :(
