Is this still the case ? I wasn't able to reproduce the LKP setup, getting some
failures. Can you provide: rust/bindings/bindings_generated.rs from the build
folder ?

sorry for false positive. we confirmed this is an issue caused by a bug in
bindgen - https://github.com/rust-lang/rust-bindgen/issues/3264

after we upgrading to bindgen-0.72.1, the issue gone.
