SubjectRe: [PATCH v5 00/10] xen-block: multi hardware-queues/rings support
>   xen/blkback: separate ring information out of struct xen_blkif
> xen/blkback: pseudo support for multi hardware queues/rings
> xen/blkback: get the number of hardware queues/rings from blkfront
> xen/blkback: make pool of persistent grants and free pages per-queue

OK, got to those as well. I have put them in 'devel/for-jens-4.5' and
are going to test them overnight before pushing them out.

I see two bugs in the code that we MUST deal with:

- print_stats () is going to show zero values.
- the sysfs code (VBD_SHOW) aren't converted over to fetch data
from all the rings.
