Subject: [PATCH v13 08/17] rust: helper: Add spin_{un,}lock_irq_{enable,disable}() helpers
Date: Mon, 13 Oct 2025 11:48:10 -0400	[thread overview]
Message-ID: <20251013155205.2004838-9-lyude@redhat.com> (raw)
In-Reply-To: <20251013155205.2004838-1-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.
