NAME
       trace_block_rq_complete - block IO operation completed by device driver

SYNOPSIS
       void trace_block_rq_complete(struct request_queue * q, struct request * rq,
                                    unsigned int nr_bytes);

ARGUMENTS
       q
           queue containing the block operation request

       rq
           block operations request

       nr_bytes
           number of completed bytes

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