  block/io: optimize bdrv_co_pwritev for small requests
  iostatus: fix comments for block_job_iostatus_reset
  block/io: Remove unused bdrv_aio_write_zeroes()
  virtio: drop duplicate virtio_queue_get_id() function
  virtio-scsi: Remove op blocker for dataplane
  virtio-blk: Remove op blocker for dataplane
