Subject: [PATCH v16 03/10] x86/arch_prctl/64: Use SYSCALL_DEFINE2 to define sys_arch_prctl
Date: Mon, 20 Mar 2017 01:16:21 -0700 [thread overview]
Message-ID: <20170320081628.18952-4-khuey@kylehuey.com> (raw)
In-Reply-To: <20170320081628.18952-1-khuey@kylehuey.com>
Use the SYSCALL_DEFINE2 macro instead of manually defining it.
