X-Received-From: 162.221.156.55 Subject: [Qemu-devel] [PATCH v4 1/9] xen: add a meaningful declaration of grant_copy_segment into xen_common.h 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: Anthony Perard , Paul Durrant , Stefano Stabellini Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RSF_0 Z_629925259 SPT_0 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="utf-8" Currently the xen_disk source has to carry #ifdef exclusions to compile against Xen older then 4.8. This is a bit messy so this patch lifts the definition of struct xengnttab_grant_copy_segment and adds it into the pre-4.8 compat area in xen_common.h, which allows xen_disk to be cleaned up.
