DAMON is a kernel framework that provides API for other subsystems or
modules in the kernel space.  The API functions have their own
kernel-doc comments, and DAMON modules including DAMON_SYSFS,
DAMON_RECLAIM, and DAMON_LRU_SORT can be used as a refernce usages.
However, kernel-doc is not very easy for beginner, and the existing
DAMON modules for real usage are bit complicated.  Add sample DAMON
modules showing basic usage of DAMON kernel API.

Note that some of the code for similar purpose that I used at kernel
summit 2021 DAMON live coding session[1] is reused here.

SeongJae Park (5):
  samples: introduce a skeleton of a sample DAMON module for working set
    size estimation
  samples/damon/wsse: implement DAMON starting and stopping
  samples/damon/wsse: implement working set size estimation and logging
  samples/damon: introduce a skeleton of a smaple DAMON module for
    proactive reclamation
  samples/damon/prcl: implement schemes setup
