From 7c81aa85eee536f36ad79339bbbc7528a49d30fe Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Mon, 1 Apr 2024 23:23:01 +0200 Subject: rust: sync: implement `Default` for `LockClassKey` In the upcoming Rust 1.78.0, Clippy suggests to implement `Default` even when `new()` is `const`, since `Default::default()` may call `const` functions even if it is not `const` itself [1]: error: you should consider adding a `Default` implementation for `LockClassKey` --> rust/kernel/sync.rs:31:5 | 31 | / pub const fn new() -> Self { 32 | | Self(Opaque::uninit()) 33 | | } | |_____^ Thus implement it.
