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.
