# Test that if we delete a snapshot, delete its parent directory, create

# another directory with the same name as that parent and then fsync either
|

# the new directory or a file inside the new directory, the fsync succeeds,
|
|
|
|
|
# the fsync log is replayable and produces a correct result.
