# Protection information test with io_uring_cmd I/O engine for nvme-ns generic
# character device.
#
# This requires nvme device to be formatted with extended LBA data size and
# protection information enabled. This can be done with nvme-cli utility.
# Replace bs below with the correct extended LBA size.
#
# 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.
