Subject: [PATCH v4 7/7] rust: time: remove unused Jiffies/Msecs helpers
Date: Thu, 23 Jul 2026 06:49:51 +0900 [thread overview]
Message-ID: <20260722214951.72941-8-tomo@flapping.org> (raw)
In-Reply-To: <20260722214951.72941-1-tomo@flapping.org>
From: FUJITA Tomonori <fujita.tomonori@gmail.com>
CondVar's wait_interruptible_timeout() and workqueue's
enqueue_delayed() have both moved from raw jiffies counts to Delta, so
nothing in the tree calls msecs_to_jiffies() or uses the Jiffies and
Msecs aliases anymore.
