Yes, I am sure. Just to clarify, I am not testing 5e7c9b84ad08. I am
testing c6af9a1191d042839e56abff69e8b0302d117988 where
`#[allow(clippy::non_send_fields_in_send_ty)]` was added on
`unsafe impl<T: Driver> Send for Registration<T> {}`.
Switching from `allow` to `expect` produced the following result on my
end:
```
$ make LLVM=1 -j $(nproc)
CLIPPY=1 DESCEND objtool
CALL scripts/checksyscalls.sh
INSTALL libsubcmd_headers
CLIPPY L rust/kernel.o
error: this lint expectation is unfulfilled

`#[allow(unfulfilled_lint_expectations)]`
