+Subject: [PATCH] vfio: Add vfio_prereg_listener_log_sync in nested stage
+
+In nested mode, we set up the stage 2 (gpa->hpa)and stage 1
+(giova->gpa) separately by vfio_prereg_listener_region_add()
+and vfio_listener_region_add(). So when marking dirty pages
+we just need to pay attention to stage 2 mappings.
+
+Legacy vfio_listener_log_sync cannot be used in nested stage.
+This patch adds vfio_prereg_listener_log_sync to mark dirty
+pages in nested mode.
