| # DESCRIPTION: | ||
| # Verify slogs are replayed correctly for cloned files. This | ||
| # test is ported from slog_replay tests for block cloning. | ||
| # | ||
| # STRATEGY: | ||
| # 1. Create an empty file system (TESTFS) | ||
| # 2. Create regular files and sync | ||
| # 3. Freeze TESTFS | ||
| # 4. Clone the file | ||
| # 5. Unmount filesystem | ||
| # <At this stage TESTFS is frozen, the intent log contains a | ||
| # complete set of deltas to replay it> | ||
| # 6. Remount TESTFS <which replays the intent log> | ||
| # 7. Compare clone file with the original file | ||
| # | ||
