Subject: [PATCH 15/24] rust: helper: Add spin_{un,}lock_irq_{enable,disable}() helpers
Date: Fri, 31 Jul 2026 13:30:16 -0700 [thread overview]
Message-ID: <20260731203031.13679-16-boqun@kernel.org> (raw)
In-Reply-To: <20260731203031.13679-1-boqun@kernel.org>
From: Boqun Feng <boqun.feng@gmail.com>
spin_lock_irq_disable() and spin_unlock_irq_enable() are inline
functions, to use them in Rust, helpers are introduced. This is for
interrupt disabling lock abstraction in Rust.
