That's right. I missed this. I will move these things to uapi. Thanks.

E.g virtio scsi differ in buffer out of out one: structvirtio_scsi_req_cmd{ ... u8 dataout[]; ... u8 datain[]; } And I would like to have a look at the spec patch. Thanks
Sure. I will send the v3 along with the spec patch. Thanks. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
