Kenneth D. Merry fd8be18f3f Fix I/O size calculation for pass(4) driver requests and add latency ... tracking. It is important to subtract the residual from the requested transfer size to see how much data was actually transferred. With tape drives in particular, it is common to request more data than is returned. Also, add I/O latency tracking for CAM requests issued by cam_periph_runccb(). If the caller supplies a struct devstat, and the I/O is a SCSI or ATA I/O, we will track the elapsed time to provide I/O latency statistics for the request. sys/cam/scsi/cam_periph.c: In cam_periph_runccb(), subtract the residual when reporting I/O totals to devstat(9) for SCSI and ATA passthrough requests. In cam_periph_runccb(), grab the I/O start time and supply the start time to devstat_end_transaction() so that it can calculate the elapsed I/O time.
