Subject: selftests/damon/_damon_sysfs: implement kdamonds stop function
Date: Tue, 25 Jun 2024 11:05:35 -0700
Implement DAMON stop function on the test-purpose DAMON sysfs interface
wrapper Python module, _damon_sysfs.py. This feature will be used by
future DAMON tests that need to start/stop DAMON multiple times.
