* cache.files=libfuse: follow traditional libfuse `direct_io`,
`kernel_cache`, and `auto_cache` arguments.
* cache.files=per-process: Enable page caching only for processes
which 'comm' name matches one of the values defined in
`cache.files.process-names`.
* cache.files=per-process: Enable page caching (equivalent to `cache.files=partial`)
only for processes which 'comm' name matches one of the values defined in
`cache.files.process-names`. If the name does not match the file open
is equivalent to `cache.files=off`.
