Starting with bindgen 0.73.2 [1], `#[allow(unnecessary_transmutes)]`
are used, even when `--rust-target 1.85` is passed.
However, the lint was introduced in Rust 1.88.0. Thus building with
older Rust versions warns like:
error: unknown lint: `unnecessary_transmutes`
--> rust/uapi/uapi_generated.rs:26294:13
|
26294 | #[allow(unnecessary_transmutes)]
| ^^^^^^^^^^^^^^^^^^^^^^
|
= note: `-D unknown-lints` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unknown_lints)]`
Thus allow `unknown_lints` in the generated bindings -- only when building
with older Rust versions.
I have asked upstream if this is intentional [1], i.e. if we are supposed
to always allow unknown lints in case `bindgen` uses such attributes,
or whether it is an oversight.
[ Emilio said it wasn't intentional -- we will work around it for now
on the kernel side. - Miguel ]
