Subject: [PATCH v2 0/2] Add atomic bool support
Date: Thu, 1 Jan 2026 12:49:20 +0900 [thread overview]
Message-ID: <20260101034922.2020334-1-fujita.tomonori@gmail.com> (raw)
This adds `bool` support to the Rust LKMM atomics.
Rust specifies that `bool` has size 1 and alignment 1 [1], so it can
be represented using an `i8` backing type.
[1] https://doc.rust-lang.org/reference/types/boolean.html
v2:
- remove AtomicImpl
- remove Safety comment about the bit patterns
- remove from_ptr() comment in cover letter
v1: https://lore.kernel.org/rust-for-linux/20251230045028.1773445-1-fujita.tomonori@gmail.com/
