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.
