That is good to know, thanks! Out-of-tree users can always be a surprise... :)

Indeed! I hope you like it -- we are taking the documentation tests in
Rust (which are a very lightweight way of writing examples which
double as tests) and generating KUnit test cases on the fly. For the
moment it is just for the `kernel` crate, but the idea is to
generalize it for modules etc.

By the way, since you saw the PR... do you know if KUnit relies (or
will rely) on "stack-dumping" functions like `longjmp`?

Cheers,
Miguel
