Date: Thu, 23 May 2013 09:49:10 -0700 Message-Id: <1369327750-28580-7-git-send-email-ddaney.cavm@gmail.com> X-Mailer: git-send-email 1.7.11.7 In-Reply-To: <1369327750-28580-1-git-send-email-ddaney.cavm@gmail.com> References: <1369327750-28580-1-git-send-email-ddaney.cavm@gmail.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2652 Lines: 99 From: David Daney The Linux Way is to return -ENOIOCTLCMD to the vfs when an unimplemented ioctl is requested. Do this in kvm_mips instead of a random mixture of -ENOTSUPP and -EINVAL.
