Convert this unit test to a KUnit test. This allows the test to benefit from the KUnit tooling. Note that care is taken to avoid test-ending assertions in worker threads, which is unsafe in KUnit (and wasn't done before this change either).
So this was something simple, and now I need to know how to operate this kunit nonsense :-(
How is that an improvement?
Hi Peter,
David enumerated some of the benefits of KUnit in another thread: https://lore.kernel.org/all/CABVgOS=KZrM2dWyp1HzVS0zh7vquLxmTY2T2Ti53DQADrW+....
My personal reason for preferring KUnit is that it's much easier to run from userspace; the tooling takes care of building, starting the VM, running the tests, and producing a human-friendly report.
Anecdotally I've seen evidence that e.g. Intel's 0-day runs all KUnit tests but not all kselftests (e.g. https://lore.kernel.org/all/202502090223.qCYMBjWT-lkp@intel.com/).
