Mark Johnston b1dd067032 vtblk: Invoke busdma completion callbacks when polling ... vtblk_poll_request() is used for kernel dumps and for fetching the block device's identifier string during device probing. In the latter case, it was not calling bus_dmamap_sync() after completing the I/O, but this is required in general. Thus: - Factor out per-request code from vtblk_queue_completed(). - Use it in vtblk_poll_request() once virtqueue_poll() finishes. - While here, assert that virtqueue_poll() returns the request that we expect.
