Subject: [PATCH v2 0/5] mm/damon/tests/core-kunit: extend existing test scenarios

Improve the KUnit test coverage for DAMON. 

The five patches in this series respectively extend damon_test_split_at(), 
damon_test_merge_two(), damon_test_merge_regions_of(), 
damon_test_split_regions_of(), and damos_test_commit_quota_goal().

Changes from v1:
- Split the original patch into five smaller patches.
- Remove a newly added region from damon_test_merge_regions_of() 
  to avoid an obvious test case.
- Restore the test case in damon_test_split_regions_of() 
  that was previously removed.

Shu Anzai (5):
  mm/damon/tests/core-kunit: verify the 'age' field in
    damon_test_split_at()
  mm/damon/tests/core-kunit: verify the 'age' and 'nr_accesses_bp'
    fields in damon_test_merge_two()
  mm/damon/tests/core-kunit: add a test case for region merge size limit
    in damon_test_merge_regions_of()
  mm/damon/tests/core-kunit: add test cases for multiple regions in
    damon_test_split_regions_of()
  mm/damon/tests/core-kunit: remove a redundant test case and add a new
    test case in damos_test_commit_quota_goal()
