[PATCH liburing 0/5] Add basic test for nvme uring passthrough commands

[Ankit Kumar <ankit.kumar@samsung.com>]

This patchset adds test/io_uring_passthrough.c to submit uring passthrough
commands to nvme-ns character device. The uring passthrough was introduced
with 5.19 io_uring.

To send nvme uring passthrough commands we require helpers to fetch NVMe
char device (/dev/ngXnY) specific fields such as namespace id, lba size.

How to run:
./test/io_uring_passthrough.t /dev/ng0n1

This covers basic write/read with verify for sqthread poll,
vectored / nonvectored and fixed IO buffers, which can be easily extended
in future.

Ankit Kumar (5):
  configure: check for nvme uring command support
  io_uring.h: sync sqe entry with 5.20 io_uring
  nvme: add nvme opcodes, structures and helper functions
  test: add io_uring passthrough test
  test/io_uring_passthrough: add test case for poll IO
