X-Received-From: 66.165.176.89 Subject: [Qemu-devel] [PATCH 05/11] xen: move xc_interface compatibility fallback further up the file X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Juergen Gross , Stefano Stabellini , Ian Jackson , Ross Lagerwall , Anthony PERARD , xen-devel@lists.xenproject.org Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP We are going to want to use the dummy xendevicemodel_handle type in new stub functions in the CONFIG_XEN_CTRL_INTERFACE_VERSION < 41000 section. So we need to provide that definition, or (as applicable) include the appropriate header, earlier in the file. (Ideally the newer compatibility layers would be at the bottom of the file, so that they can naturally benefit from the compatibility layers for earlier version. But that's rather too much for this series.) No functional change.
