Subject: Re: [PATCH v4] rust: kernel: introduce `unsafe_precondition_assert!`
 macro

If someone's referring to it in the future, this was doctest issue.

It’s actually the second time I’ve hit it.
On my end, this error wasn't occurring when compiling the kernel.

What I was missing:
1. Enable `Kernel Hacking > Kernel Testing and Coverage > KUnit`
2. Enable Doctest in `Rust hacking > Doctests for the 'kernel' crate`

I can now reproduce capture the issue locally.
Won't happen again :)
