Nir Soffer reported that virtio-scsi,iothread=... consumes 100% CPU in QEMU
7.0. This patch series addresses two bugs in hw/scsi/virtio-scsi.c (see patches
1 & 2) and follows up with code cleanups.
Stefan Hajnoczi (6):
virtio-scsi: fix ctrl and event handler functions in dataplane mode
virtio-scsi: don't waste CPU polling the event virtqueue
virtio-scsi: clean up virtio_scsi_handle_event_vq()
virtio-scsi: clean up virtio_scsi_handle_ctrl_vq()
virtio-scsi: clean up virtio_scsi_handle_cmd_vq()
virtio-scsi: move request-related items from .h to .c
