Like tell_host(), stats_handle_request() ignores the return value of virtqueue_add_outbuf() and kicks the queue regardless. The same "we should always be able to add one buffer to an empty queue" assumption does not hold once the virtqueue has been broken (e.g. on device shutdown), where the add fails with -EIO. Unlike tell_host() it does not wait_event() afterwards so it cannot hang, but it still kicks a queue with nothing queued. Warn and bail out on failure, mirroring tell_host() and virtballoon_free_page_report(). Suggested-by: David Hildenbrand <david@kernel.org> Signed-off-by: Denis V.
