[v2,3/3] generic/396: test correct d_type values

Commit Message

Amir Goldstein Dec. 20, 2016, 1:17 p.m. UTC

Verify correct d_type values of dir entries.

This test does NOT require that file system support the filetype feature.
It verifies that either all file types are reported as DT_UNKNOWN
or that all file types are reported correctly.

For fs for which we know how to test the filetype feature (xfs|ext*)
verify getting DT_UNKNOWN IFF feature is disabled.

Verify special dir entries . and .. are always reported as DT_DIR.
