NUMA nodes in the physical address space, special memory objects in the virtual address space, and monitoring target specific efficient monitoring results snapshot retrieval could be examples of such use cases. This patchset extends DAMOS filters feature for such cases, by implementing two more filter types, namely address ranges and DAMON monitoring types. Patches sequence ---------------- The first seven patches are for the address ranges based DAMOS filter. The first patch implements the filter feature and expose it via DAMON kernel API. The second patch further expose the feature to users via DAMON sysfs interface. The third and fourth patches implement unit tests and selftests for the feature. Three patches (fifth to seventh) updating the documents follow. The following six patches are for the DAMON monitoring target based DAMOS filter. The eighth patch implements the feature in the core layer and expose it via DAMON's kernel API. The ninth patch further expose it to users via DAMON sysfs interface. Tenth patch add a selftest, and two patches (eleventh and twelfth) update documents.
