Merge tag 'for-5.19/io_uring-passthrough-2022-05-22' of git://git.kernel.dk/linux-block
Pull io_uring NVMe command passthrough from Jens Axboe:
"On top of everything else, this adds support for passthrough for
io_uring.
The initial feature for this is NVMe passthrough support, which allows
non-filesystem based IO commands and admin commands.
To support this, io_uring grows support for SQE and CQE members that
are twice as big, allowing to pass in a full NVMe command without
having to copy data around. And to complete with more than just a
single 32-bit value as the output"
