DESCRIPTION

24       The block_rq_complete tracepoint event indicates that some portion of
25       operation request has been completed by the device driver. If the
26       rq->bio is NULL, then there is absolutely no additional work to do for
27       the request. If rq->bio is non-NULL then there is additional work
28       required to complete the request.
