Subject: [RFC PATCH 03/30] softirq: Implement local_softirq_pending() below softirq vector definition
Date:   Thu, 11 Oct 2018 01:11:50 +0200
Message-Id: <1539213137-13953-4-git-send-email-frederic@kernel.org>
In-Reply-To: <1539213137-13953-1-git-send-email-frederic@kernel.org>
References: <1539213137-13953-1-git-send-email-frederic@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The future extensions of this API are going to depend on the vector
definitions. So order the code accordingly.
