+/*
+ * First, avoid forward references to `enum` types.
+ *
+ * This workarounds a `bindgen` issue with them:
+ * <https://github.com/rust-lang/rust-bindgen/issues/3179>.
+ *
+ * Without this, the generated Rust type may be the wrong one (`i32`) or
+ * the proper one (typically `c_uint`) depending on how the headers are
+ * included, which in turn may depend on the particular kernel configuration
+ * or the architecture.
+ *
+ * The alternative would be to use casts and likely an
+ * `#[allow(clippy::unnecessary_cast)]` in the Rust source files. Instead,
+ * this approach allows us to keep the correct code in the source files and
+ * simply remove this section when the issue is fixed upstream and we bump
+ * the minimum `bindgen` version.
+ *
+ * This workaround may not be possible in some cases, depending on how the C
+ * headers are set up.
