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.
