# DESCRIPTION:
# Verify slogs are replayed correctly for encrypted cloned files.
# This test is ported from slog_replay tests for block cloning.
#
# STRATEGY:
# 1. Create an encrypted 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 encrypted TESTFS <which replays the intent log>
# 7. Compare clone file with the original file
