# Protection information test with io_uring_cmd I/O engine for nvme-ns generic
# character device.
#
# This requires nvme device to be formatted with separate metadata buffer and
# protection information enabled. This can be done with nvme-cli utility.
# Replace md_per_io_size as per the required metadata buffer size for each IO.
#
# First we sequentially write to the device, without protection information
# action being set. FIO will generate and send necessary protection
# information data as per the protection information check option. Later on we
# sequentially read and verify the device returned protection information data.
