Hi all:

This series implements packed virtqueues which were described
at [1]. In this version we try to address the performance regression
saw by V2. The root cause is packed virtqueue need more times of
userspace memory accesssing which turns out to be very
expensive. Thanks to the help of 7f466032dc9e ("vhost: access vq
metadata through kernel virtual address"), such overhead cold be
eliminated. So in this version, we can see about 2% improvement for
packed virtqueue on PPS.
Great job, thanks!
Pls allow a bit more review time than usual as this is a big patchset.
Should be done by Tuesday.
-next material anyway.


Sure, just to confirm, I think this should go for your vhost tree?.

Thanks
