Subject: [RFC PATCH 02/30] arch/softirq: Rename softirq_pending fields to softirq_data
Date: Thu, 11 Oct 2018 01:11:49 +0200 [thread overview]
Message-ID: <1539213137-13953-3-git-send-email-frederic@kernel.org> (raw)
In-Reply-To: <1539213137-13953-1-git-send-email-frederic@kernel.org>
We are going to extend the softirq bits with an enabled vector mask.
Provide the field with a more generic name to later layout the pending
states on the lower bits and the enabled states on the higher bits.
