SeongJae Park f37ab7f595 UPSTREAM: mm/damon/core: use better timer mechanisms selection threshold
Patch series "mm/damon: Trivial fixups and improvements".

This patchset contains trivial fixups and improvements for DAMON and its
kunit/kselftest tests.

This patch (of 11):

DAMON is using hrtimer if requested sleep time is <=100ms, while the
suggested threshold[1] is <=20ms.  This commit applies the threshold.
