When an assertion is failed, sysfs.py DAMON selftest immediately exits the test program leaving the DAMON running behind. Many of the following tests need to start DAMON on their own. But because DAMON that was started by sysfs.py is still running, those start attempts fail, and the tests are failed or skipped. Update sysfs.py to stop DAMON before exiting the test program due to the assertion failure.
