*Optional override for maximum file name length*

Type: ``int``

Help
====

.. code-block:: none

    Specify the maximum file name allowed across all enabled file
    system types.  Zero or a negative value selects the maximum
    file name length for enabled in-tree file systems.  This
    default may be inappropriate when registering an out-of-tree
    file system.  Selecting a value less than the actual length
    supported by a file system may result in memory access
    violations.
