Hi Changpeng:
=E2=80=82=E2=80=82=E2=80=82=E2=80=82=E2=80=82 Thanks for your reply!
=E2=80=82=E2=80=82=E2=80=82=E2=80=82=E2=80=82 Will community accept the com=
mits as using multiple cores for a virtio-blk device?
=E2=80=82=E2=80=82=E2=80=82=E2=80=82=E2=80=82=E2=80=82If not,  what are the=
 main concerns?

I think that's the only benefit by using multiple cores for a virtio-blk de=
vice, if your tests case is for a VM,
Actually you can add multiple devices to this VM.
