The data in/out buffers are accessible via tht req.iov[] array. iov_cnt contains the number of entries in iov[] needed to describe either the Data-In or Data-Out buffers. For bidirectional commands, iov_cnt specifies how many iovec -entries cover the Data-Out area, and iov_bidi_count specifies how many +entries cover the Data-Out area, and iov_bidi_cnt specifies how many iovec entries immediately after that in iov[] cover the Data-In area. Just like other fields, iov.iov_base is an offset from the start of the region.
