Subject: [GIT PULL] [PATCH 00/13] Rust atomic changes for v7.1
Date: Tue, 3 Mar 2026 12:16:48 -0800 [thread overview]
Message-ID: <20260303201701.12204-1-boqun@kernel.org> (raw)
Hi Peter,
Please pull these changes of Rust atomic in v7.1 into tip/locking/core.
Major changes are the atomic pointer support and a boolean-like
AtomicFlag type (using a byte if arch support efficient xchg/cmpxchg
over bytes otherwise 4 bytes). Thanks!
Regards,
Boqun

rust: atomic: Update a safety comment in impl of `fetch_add()` (2026-03-03 11:55:57 -0800)
----------------------------------------------------------------
Rust atomic changes for v7.1
* Add Atomic<ptr> support.
* Add an AtomicFlag type for boolean-like usage with
architecture-specific performance optimization.
* Add unsafe atomic operations over raw pointers.
* Add `fetch_sub()` for atomic types.
* Documentation and example improvements.
