Ok, you're essentially saying that kernel code is too important to be tested. Honestly, that logic sounds like Effective Altruism levels of twisted to me.
So if tests don't cut it, what does the Kernel community then do instead of testing to verify correctness?

That's exactly the kind of code that needs tests.
What happens if someone changes some code that affects the read call and expects it to run on said billion of devices?
