In each region directory, you will find four files (``start``, ``end``,

``nr_accesses``, and ``age``).  Reading the files will show the start and end

addresses, ``nr_accesses``, and ``age`` of the region that corresponding

DAMON-based operation scheme ``action`` has tried to be applied.

In each region directory, you will find five files (``start``, ``end``,

``nr_accesses``, ``age``, and ``sz_filter_passed``).  Reading the files will

show the properties of the region that corresponding DAMON-based operation

scheme ``action`` has tried to be applied.
