Subject: _damon_sysfs: implement commit() for online parameters update
Date: Tue, 25 Jun 2024 11:05:37 -0700
Users can update DAMON parameters while it is running, using 'commit'
DAMON sysfs interface command. For testing the feature in future tests,
implement a function for doing that on the test-purpose DAMON sysfs
interface wrapper Python module.
