From 11cd1a8b8cad1acfc140d9acce93762a9c140b20 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 14 Nov 2010 17:31:52 +0200 Subject: vhost/net: fix rcu check usage Incorrect rcu check was used as rcu isn't done under mutex here. Force check to 1 for now, to stop it from complaining. Signed-off-by: Michael S.
