Its filename was selftests-damon-damon_nr_regions-sort-collected-regiosn-before-checking-with-min-max-boundaries.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park Subject: selftests/damon/damon_nr_regions: sort collected regiosn before checking with min/max boundaries Date: Tue, 25 Feb 2025 14:23:33 -0800 damon_nr_regions.py starts DAMON, periodically collect number of regions in snapshots, and see if it is in the requested range. The check code assumes the numbers are sorted on the collection list, but there is no such guarantee. Hence this can result in false positive test success. Sort the list before doing the check.
