    Subject[PATCH 00/13] Extedn DAMOS filters for address ranges and DAMON monitoring targets
    Date
    Changes from RFC[1]
    - Rebase on latest mm-unstable
    - Add base-commit

    ----

    There are use cases that need to apply DAMOS schemes to specific address
    ranges or DAMON monitoring targets. 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.
