Nope, I already mentioned this :

Please take a look at 2613af0ed18a11d5c566a81f9a6510b73180660a
("virtio_net: migrate mergeable rx buffers to page frag allocators")

This patch should simply be reverted.  You guys steam-rolled over
the virtio_net people's concerns that this seriously impacts virt
performance.

Have you followed netdev traffic lately ?

virtio_net performance is better than before, and we did no revert,
thank you.

The last email I saw from Michael Tsirkin he still wasn't happy
that your patch does not degrade virt performance.  Where is the
reply to that?

Cheers,
