virtio_pci_set_guest_notifiers() now takes an additional argument to specify the number of virtqueues to assign a guest notifier for. This causes a build breakage for CONFIG_VIRTIO_BLK_DATA_PLANE builds: /home/mdroth/w/qemu2.git/hw/dataplane/virtio-blk.c: In function ‘virtio_blk_data_plane_start’: /home/mdroth/w/qemu2.git/hw/dataplane/virtio-blk.c:451:47: error: too few arguments to function ‘s->vdev->binding->set_guest_notifiers’ /home/mdroth/w/qemu2.git/hw/dataplane/virtio-blk.c: In function ‘virtio_blk_data_plane_stop’: /home/mdroth/w/qemu2.git/hw/dataplane/virtio-blk.c:511:5: error: too few arguments to function ‘s->vdev->binding->set_guest_notifiers’ make[1]: *** [hw/dataplane/virtio-blk.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [subdir-x86_64-softmmu] Error 2 Fix this by passing 1 as the number of virtqueues to assign notifiers for.
