Subject: mm/damon/tests/core-kunit: remove DAMON_MIN_REGION redefinition
Date: Wed, 12 Nov 2025 07:41:09 -0800

A few DAMON core functions including damon_set_regions() were hard-coded to use DAMON_MIN_REGION as their regions management granularity. For simple and human-readable unit tests' expectations, DAMON core layer kunit test re-defines DAMON_MIN_REGION to '1'.

A previous patch series [1] has removed the hard-coded part but kept the redefinition and updated related function calls to explicitly use DAMON_MIN_REGION. Remove the unnecessary redefinition and update relevant function calls to pass literals (number '1') instead of the DAMON_MIN_REGION.
