The quilt patch titled
Subject: mm/damon/tests/core-kunit: extend set_regions() test for error case
has been removed from the -mm tree. Its filename was
mm-damon-tests-core-kunit-extend-set_regions-test-for-error-case.patch

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/damon/tests/core-kunit: extend set_regions() test for error case
Date: Tue, 1 Sep 2026 22:47:39 -0700
damon_test_set_regions_for() is designed to test only success-expected
damon_set_regions() calls. Extend it to cover error-expected calls, too.
