This 29# test is ported from slog_replay tests for block cloning. 30# 31# STRATEGY: 32# 1. Create an empty file system (TESTFS) 33# 2. Create regular files and sync 34# 3. Freeze TESTFS 35# 4. Clone the file 36# 5. Unmount filesystem 37# <At this stage TESTFS is frozen, the intent log contains a 38# complete set of deltas to replay it> 39# 6. Remount TESTFS <which replays the intent log> 40# 7.
