This is an interesting change. We can keep this open for discussion here. If required, I can work on this in the future.quoted
Yes, we should in general try moving all test modules out of the core.If you're working on this please make sure to take a look at how the various automated testing systems cope with modules built under selftests (personally I think everything I care about uses tuxmake builds, but there's other stuff out there). I think the answer for a bunch of them right now is badly, but I didn't actually go check.
There is huge discussion in the past on converting test modules into kunit modules [1]. Selftests is not a correct place to keep kernel modules. People have moved a lot of such modules. But new test modules get added over time again. [1] https://lore.kernel.org/all/20250207-bitmap-kunit-convert-v1-0-c520675343b6@gmail.com/ (local) -- Thanks, Usama
