2011-07-18iov: Update parameter usage in iov_(to|from)_buf()Hannes Reinecke1-5/+5
iov_to_buf() has an 'offset' parameter, iov_from_buf() hasn't. This patch adds the missing parameter to iov_from_buf(). It also renames the 'offset' parameter to 'iov_off' to emphasize it's the offset into the iovec and not the buffer.
