The patch series (now posted) makes all aio APIs use iovecs. The current non-iovec based SG API would require some nasty shims allocating nested aiocbs. Or we could just make the sg aio methods fake-ioveced which is the solution I had before your split, always adding a one-element iovec to the scsi-generic request structure.
