# Test filetype feature
#
# This test does NOT require that file system support the d_type feature.
# It verifies that file types are reported as either DT_UNKNOWN or as
# the actual file type. For example, special dir entries . and .. MAY be
# reported as DT_UNKNOWN IF filetype feature is disabled (ext4), but MAY
# also be reported as DT_DIR in this case (xfs).
#
# For fs for which we know how to test the filetype feature (xfs|ext*)
# verify getting DT_UNKNOWN IFF feature is disabled.
