Subject: [PATCH 0/2] Support `likely`, `unlikely` and `cold_path`
Date: Sun, 8 Feb 2026 23:46:57 +0100 [thread overview]
Message-ID: <20260208224659.18406-1-ojeda@kernel.org> (raw)
Rust 1.95.0 stabilized the `cold_path` feature, which means that it is
a good time to add the support for this pervasive feature in C.
The functions should work as expected for all Rust >= 1.84.0, which
includes our future bumped Rust minimum version. For older versions,
they are a no-op.
Miguel Ojeda (2):
rust: prelude: use the "kernel vertical" imports style
rust: std_vendor: add `{likely,unlikely,cold_path}()`
init/Kconfig | 6 ++
