When the fault injection framework introduces an error to the data block, the current code queries the SD card to find the number of blocks actually programmed. This value would be as requested by the generic block layer. So the entire request would be completed. Say, request 0 is pulled from queue and submitted. When this is being processed, request 1 is pulled from queue and prepared. Request 0 though is successful, fault-injection framework injects an error and modifies the bytes_xferred variable to a random value less than requested transfer. Request 1 is not processed and during the handling of error, the SD card is queried for the actual bytes programmed. This would be the correct value. Thus blk_end_request would complete this request and the control would return to fetch request 2. In this process, request 1 is not processed at all and the application waits indefinitely for request 1 to be processed. No further requests are issued to the queue. This patch identifies, if the fault injection-framework has inserted an error to this request and doesn't query the card and uses bytes_xferred to complete the request.
