| # FS QA Test 402 |
| # |
| # Tests to verify policy for filesystem timestamps for |
| # supported ranges: |
| # 1. Verify filesystem rw mount according to sysctl |
| # timestamp_supported. |
| # 2. Verify timestamp clamping for timestamps beyond max |
| # timestamp supported. |
| # |
| # Exit status 1: either or both tests above fail. |
| # Exit status 0: both the above tests pass. |
