Subject: [PATCH v12 06/15] rust: helper: Add spin_{un,}lock_irq_{enable,disable}() helpers
Date: Thu, 17 Jul 2025 15:15:45 -0400 [thread overview]
Message-ID: <20250717191719.2076270-7-lyude@redhat.com> (raw)
In-Reply-To: <20250717191719.2076270-1-lyude@redhat.com>
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.
