Patch series "mm/damon/tests: add more tests for online parameters commit". A DAMON feature called parameters "commit" allows DAMON API callers and ABI users to update nearly every DAMON parameter while DAMON is running. This is being used for flexible DAMON use cases such as taking a snapshot of the monitoring results with minimum overhead, or adjusting access-aware system operations (DAMOS) for user-space driven auto-tuning or investigations. Compared to the usefulness of the feature and size of the implementation, the test coverage is pretty small. Only the filter commit part has a single test case, namely damos_test_commit_filter(). Actually, we found and fixed a few bugs of the feature in the past. The single existing test was also added to avoid reintroduction of a found bug. Add more unit tests for the feature. First four patches (1-4) refactor and extend the existing test for DAMOS filter commit for multiple test cases. Next three patches (5-7) add tests for DAMOS quota commit. Next two patches (8 and 9) refactor damos_commit_dests() for ease of code reading and test writing, and implement a new unit test of the function that is being refactored in a test-friendly way. Final two patches (10 and 11) further add new unit tests for damos_commit() and damon_commit_target_regions(). This patch (of 11): damos_test_commit_filter() is dynamically allocating test-purpose DAMOS filters. Allocation failure checks are making the code longer, complicated, and difficult to extend for more test cases. Refactor the code to remove the dynamic allocation.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
