Subject: Re: [PATCH v2 1/2] virtio_net: fix error handling for mergeable

From: "Michael S. Tsirkin" <>
Date: Thu, 28 Nov 2013 13:30:55 +0200

> Eric Dumazet noticed that if we encounter an error

> the result is almost sure to be loss of networking.
> Jason Wang noticed that we also leak a page and that we don't decrement
> the rq buf count, so we won't repost buffers (a resource leak).
> Fix both issues.
