mm/damon/tests/core-kunit: add a test for damon_commit_ctx()

Browse source

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

Since commit c80f46ac22 ("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
c80f46ac22 ("mm/damon/core: disallow non-power of two min_region_sz")
functions as expected.
