* for these files are not cleared.
* The library will check consistency of status_flags when opening
* a file with superblock >= v3 and will return error accordingly.
* The library will not check status_flags when opening a file
* with < v3 superblock.
*
* These files are used by "h5clear" to see if the tool clears
* status_flags properly so users can open the files afterwards.
