Subject: mm/damon/tests/core-kunit: test committing psi goal to psi goal

Patch series "mm/damon: fix misc bugs in kunit, quota goals and sysfs
refresh_ms".

DAMOS quota goals commit unit test is mistakenly not testing a test case
that was designed to test.  DAMOS quota goals and DAMON sysfs refresh_ms
file have bugs that can produce non critical but still unexpected
behaviors.  Fix the bugs.

Patch 1 fixes the DAMOS quota goals commit unit test to cover a mistakenly
uncovered case.  Patches 2 and 3 fix the bugs in DAMOS PSI goal
initialization and eligible_mem_bp online commit, respectively.  Patch 4
fixes the bug in DAMON sysfs refresh_ms file handling.


This patch (of 4):

damon_test_commit_quota_goal_for() is set to test committing a new psi
goal on an existing psi goal.  However, damon_test_commit_quota_goal() is
mistakenly not covering the test case.  Add the test case.
