56 If the media device supports :ref:`requests <media-request-api>`, then
57 this request ioctl can be used to queue a previously allocated request.
59 If the request was successfully queued, then the file descriptor can be
60 :ref:`polled <request-func-poll>` to wait for the request to complete.
62 If the request was already queued before, then ``EBUSY`` is returned.
63 Other errors can be returned if the contents of the request contained
65 common error codes. On error both the request and driver state are unchanged.
67 Once a request is queued, then the driver is required to gracefully handle
