X-Received-From: 195.75.94.113 Cc: Stefan Hajnoczi , Luiz Capitulino Subject: [Qemu-devel] [PATCH v2 1/3] qerror: add check-qerror.sh to verify alphabetical order X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org We're supposed to keep qerror definitions and table entries in alphabetical order. In practice this is not checked. I haven't found a nice way to integrate this into the makefile yet but we can at least have this script which verifies that qerrors are in alphabetical order.
