Subject: [PATCH -next v1 08/12] rcu: Simplify rcu_do_batch() by applying clamp()
Date: Mon, 11 May 2026 19:54:44 +0200 [thread overview]
Message-ID: <20260511175448.153326-9-urezki@gmail.com> (raw)
In-Reply-To: <20260511175448.153326-1-urezki@gmail.com>
From: "Paul E. McKenney" <paulmck@kernel.org>
This commit replaces a nested ?: sequence with clamp(). This does not
reduce the number of lines of code, but it does simplify the line that
it modifies.
