From 656473003bc7e056c3bbd4a4d9832dad01e86f76 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 29 Aug 2014 14:01:17 +0200 Subject: KVM: forward declare structs in kvm_types.h Opaque KVM structs are useful for prototypes in asm/kvm_host.h, to avoid "'struct foo' declared inside parameter list" warnings (and consequent breakage due to conflicting types). Move them from individual files to a generic place in linux/kvm_types.h.
