This series adds async passthrough capability for nvme block-dev over iouring_cmd. The patches are on top of Jens uring-cmd branch: https://git.kernel.dk/cgit/linux-block/log/?h=io_uring-fops.v3 Application is expected to allocate passthrough command structure, set it up traditionally, and pass its address via "block_uring_cmd->addr". On completion, CQE is posted with completion-status preceding any ioctl specific buffer/field update.
