Could you take a look at these patches or the first two/three only? With this fix merged, some work can be started to extend submitting I/O as batch to multi-lun SCSI case, and this kind of optimization can't be done by vhost-scsi at all. Also multi-queue patches depend on these patches too. The 1st one has one line conflict with io_cancel() against QEMU master, and please let me know if you need me to resend or other comments. Thanks, -- Ming Lei
