From dd93938a92dc067aba70c401bdf2e50ed58083db Mon Sep 17 00:00:00 2001 From: Kyle Huey Date: Mon, 20 Mar 2017 01:16:20 -0700 Subject: [PATCH] x86/arch_prctl: Rename 'code' argument to 'option' MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The x86 specific arch_prctl() arbitrarily changed prctl's 'option' to 'code'. Before adding new options, rename it.
