10 * First, avoid forward references to `enum` types.
11 *
12 * This workarounds a `bindgen` issue with them:
13 * <https://github.com/rust-lang/rust-bindgen/issues/3179>.
14 *
15 * Without this, the generated Rust type may be the wrong one (`i32`) or
16 * the proper one (typically `c_uint`) depending on how the headers are
17 * included, which in turn may depend on the particular kernel configuration
18 * or the architecture.
19 *
20 * The alternative would be to use casts and likely an
21 * `#[allow(clippy::unnecessary_cast)]` in the Rust source files. Instead,
22 * this approach allows us to keep the correct code in the source files and
23 * simply remove this section when the issue is fixed upstream and we bump
24 * the minimum `bindgen` version.
25 *
26 * This workaround may not be possible in some cases, depending on how the C
27 * headers are set up.
