The return code is 0 if success.I mod the code a bit and then run fio very well.
I think if you fix this bug, the path will be nearly pefect!!
ret = rbd_aio_get_return_value(fri->completion);
//printf("ret=%ld\n", ret);
//if (ret != (int) io_u->xfer_buflen) {
if (ret != 0) {
if (ret >= 0) {
io_u->resid = io_u->xfer_buflen - ret;
io_u->error = 0;
} else
io_u->error = ret;
}
