Hi Brendan,
Actually https://patchwork.kernel.org/patch/11724995/ solves my problem with unsigned int, since I can customize the Expected message with this patch.
I think you can ignore this patch :)
Got it. Sounds good :-)

Some tests, such as overflow_kunit(), uses unsigned int, But kunit_binary_assert_format() only prints signed int, this commit also deals with the unsigned int print.
Oops, Thanks! I'll fix it.

I agree that you found a bug here; however, I disagree that this is the correct fix. Given that the value is stored as a long long; isn't the value always stored as a signed value? So if the value overflows, won't it still not pass the check you have here?
