Subject: [PATCH 11/32] softirq: Macrofy softirq vectors
Date: Tue, 12 Feb 2019 18:14:02 +0100 [thread overview]
Message-ID: <20190212171423.8308-12-frederic@kernel.org> (raw)
In-Reply-To: <20190212171423.8308-1-frederic@kernel.org>
Define the softirq vectors through macros so that we can later include
them in the automated definition of lockdep usage states.
