This adds a new io_uring interface to exchange additional integrity/pi
metadata with read/write.

Example program for using the interface is appended below [1].

The patchset is on top of block/for-next.

Testing has been done by modifying fio:
https://github.com/SamsungDS/fio/tree/priv/feat/pi-test-v11

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.

FWIW, we’re interested [1] in helping get this part properly tested as well.
We're already running blktests in CI as part of kdevops, regularly testing
against both linux-next and Linus' latest tags [2].

Shin'ichiro, the current CI implementation is still experimental (we are missing
a few things like archive results and dashboard reporting) but we hope we can
discuss soon the possibility to automatically reporting tests results to the
mailing list
