before in February 2023.  Read the cover letter of this patch series for

prevent unnecessary noises from the tests.

Building and running the subsuite 'damon' of kselftest, shows the
following issues:
 selftests: damon: debugfs_attrs.sh
  /sys/kernel/debug/damon not found

By creating a config file enabling DAMON fragments in the
selftests/damon/ directory the tests pass.
