-Currently, anonymous page, memory cgroup, and address range type filters are
-supported by the feature.  Some filter target types can require additional
-arguments.  For example, the memory cgroup filter type asks users to specify
-the file path of the memory cgroup for the filter, while the address range type
-asks the start and end addresses of the range.  Hence, users can apply specific
-schemes to only anonymous pages, non-anonymous pages, pages of specific
-cgroups, all pages excluding those of specific cgroups, pages in specific
-address range, and any combination of those.

-To handle filters efficiently, the address range type filter is handled by the
-core layer, while others are handled by operations set.  If a memory region is
-filtered by the core layer-handled filter, it is not counted as the scheme has
-tried to the region.  In contrast, if a memory regions is filtered by an
-operations set layer-handled filter, it is counted as the scheme has tried.
-The difference in accounting leads to changes in the statistics.
