Subject: mm/damon/tests/core-kunit: add a test for damon_commit_ctx()
Date: Sat, 7 Mar 2026 11:42:20 -0800

Patch series "mm/damon: test and document power-of-2 min_region_sz requirement".

Since commit c80f46ac228b ("mm/damon/core: disallow non-power of two min_region_sz"), min_region_sz is always restricted to be a power of two. Add a kunit test to confirm the functionality. Also, the change adds a restriction to addr_unit parameter. Clarify it on the document.

This patch (of 2):

Add a kunit test for confirming the change that is made on commit c80f46ac228b ("mm/damon/core: disallow non-power of two min_region_sz") functions as expected.
