Do you plan to submit it? It would also be extremely useful to have a testing using it in blktests, because it seems like we don't have any test coverage for the read/write with metadata code at the moment. Just bringing this up because I want to be able to properly test the metadata side of the nvme/block support for the new DMA mapping API and I'm Ñ•truggling to come up with good test coverage.
