Patch Sequence ============== The first patch (patch 1) implements two new quota goal metrics on core layer and expose it to DAMON core kernel API. The second and third ones (patches 2 and 3) further link it to DAMON sysfs interface. Three following patches (patches 4-6) document the new feature and sysfs file on design, usage, and ABI documents. The final one (patch 7) implements a working version of a self-tuned DAMON-based memory tiering solution in an incomplete but easy to understand form as a kernel module under samples/damon/ directory.
