| # FS QA Test 037 |
| # |
| # Test mount error cases with option index=on |
| # |
| # - Upper/lower mismatch |
| # - Index/upper mismatch |
| # |
| # With index=on, lowerdir and upperdir are verified using a file handle |
| # stored in trusted.overlay.origin xattr in upperdir and indexdir. |
| # |
| # Failure to verify lowerdir/upperdir on mount results in ESTALE. |
