Date: Wed, 9 Sep 2015 14:08:11 -0700 Message-Id: <1441832902-28993-3-git-send-email-palmer@dabbelt.com> X-Mailer: git-send-email 2.4.6 In-Reply-To: <1441832902-28993-1-git-send-email-palmer@dabbelt.com> References: <2644177.lVCYzIBfPW@wuerfel> <1441832902-28993-1-git-send-email-palmer@dabbelt.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I think this change actually doesn't do anything: __NR_fork was still being defined either way, and on my machine fork() in comes from libc. That said, I don't think there's any way to determine this automatically, so this at least quiets the checker.
