> CreateEditsLog generates non-standard transactions. In real life first transaction that
creates a file does not contain blocks. While CreateEditsLog adds blocks to this transaction.
Change CreateEditsLog to produce real-life transaction. 
> Also cleanup unused parameters for {{FSDirectory.updateFile()}}.
