This series implements VIRTIO_F_IN_ORDER support for vhost-net. This
feature is designed to improve the performance of the virtio ring by
optimizing descriptor processing.

Benchmarks show a notable improvement. Please see patch 3 for details.
You tagged these as net-next but just to be clear -- these don't apply
for us in the current form.
Will rebase and send a new version.

Thanks
Indeed these look as if they are for my tree (so I put them in
linux-next, without noticing the tag).
I think that's also fine.

Do you prefer all vhost/vhost-net patches to go via your tree in the future?

(Note that the reason for the conflict is because net-next gets UDP
GSO feature merged).
FTR, I thought that such patches should have been pulled into the vhost
tree, too. Did I miss something?
See: https://www.spinics.net/lists/netdev/msg1108896.html
I'm sorry I likely was not clear in my previous message. My question is:
any special reason to not pull the UDP tunnel GSO series into the vhost
tree, too?

Thanks,

Paolo
Paolo I'm likely confused. That series is in net-next, right?
So now it would be work to drop it from there, and invalidate
all the testing it got there, for little benefit -
the merge conflict is easy to resolve.
