From 72952cc0614b61650b2b13f57752a6dd82cbeae5 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 6 Dec 2016 06:01:41 +0200 Subject: [PATCH] vhost: add missing __user annotations Several vhost functions were missing __user annotations on pointers, causing sparse warnings. Fix this up. sparse also warns about vhost_process_iotlb_msg which is local and should be static. Fix that up as well. Signed-off-by: Michael S.
