It looks like this never got into upstream fio. 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 ѕtruggling to come up with good test coverage.
