DAMON recently introduced probes and probe weights. Add kunit and selftests for ensuring the parameters for features can be set using the core API and the sysfs ABI, respectively. This patch (of 6): Add kunit test to ensure damon_commit_filter() updates destination filter as expected for valid inputs.
