From 05cef2c4a421ca09ab9761a95e61423e59e5bfb1 Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Fri, 27 Sep 2024 18:44:14 +0200 Subject: rust: kunit: use C-string literals to clean warning Starting with upstream Rust commit a5e3a3f9b6bd ("move `manual_c_str_literals` to complexity"), to be released in Rust 1.83.0 [1], Clippy now warns on `manual_c_str_literals` by default, e.g.: error: manually constructing a nul-terminated string --> rust/kernel/kunit.rs:21:13 | 21 | b"\x013%pA\0".as_ptr() as _, | ^^^^^^^^^^^^^ help: use a `c""` literal: `c"\x013%pA"` | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#manual_c_str_literals = note: `-D clippy::manual-c-str-literals` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(clippy::manual_c_str_literals)]` Apply the suggestion to clean up the warnings.
