    Subject[PATCH 0/6] mm/damon/schemes: Extend stats for better online analysis and tuning
    Date
    To help online access pattern analysis and tuning of DAMON-based
    Operation Schemes (DAMOS), DAMOS provides simple statistics for each
    scheme. Introduction of DAMOS time/space quota further made the tuning
    easier by making the risk management easier. However, that also made
    understanding of the working schemes a little bit more difficult.

    For an example, progress of a given scheme can now be throttled by not
    only the aggressiveness of the target access pattern, but also the
    time/space quotas. So, when a scheme is showing unexpectedly slow
    progress, it's difficult to know by what the progress of the scheme is
    throttled, with currently provided statistics.

    This patchset extends the statistics to contain some metrics that can be
    helpful for such online schemes analysis and tuning (patches 1-2),
    exports those to users (patches 3 and 5), and add documents (patches 4
    and 6).
