From 4d0cf552d3a9585f380e8abdc313e4d416a56aa0 Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Thu, 24 May 2018 18:33:33 +0800 Subject: vhost-user: introduce shared vhost-user state When multi queue is enabled e.g. for a virtio-net device, each queue pair will have a vhost_dev, and the only thing shared between vhost devs currently is the chardev. This patch introduces a vhost-user state structure which will be shared by all vhost devs of the same virtio device. Signed-off-by: Tiwei Bie Signed-off-by: Michael S. Tsirkin Reviewed-by: Michael S.
