I had that conversation with Meta's block folks who want to do something similar with io_uring and the only option is an an allocator for memory that is known DMAable, e.g. through dma-bufs. You guys really all need to get together and come up with a scheme that actually works instead of piling these hacks over hacks.

a saner API for allocating DMA addressable pages v2
Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. I'm still a
