Subject: [PATCH v16 02/10] x86/arch_prctl: Rename 'code' argument to 'option'
Date: Mon, 20 Mar 2017 01:16:20 -0700 [thread overview]
Message-ID: <20170320081628.18952-3-khuey@kylehuey.com> (raw)
In-Reply-To: <20170320081628.18952-1-khuey@kylehuey.com>
arch_prctl arbitrarily changed prctl's 'option' to 'code'. Now that we're
adding additional options, fix that.
