Marc Zyngier 7ddfd3e0df KVM: Enforce error in ioctl for compat tasks when !KVM_COMPAT ... The current behaviour of the compat ioctls is a bit odd. We provide a compat_ioctl method when KVM_COMPAT is set, and NULL otherwise. But NULL means that the normal, non-compat ioctl should be used directly for compat tasks, and there is no way to actually prevent a compat task from issueing KVM ioctls. This patch changes this behaviour, by always registering a compat_ioctl method, even if KVM_COMPAT is not selected. In that case, the callback will always return -EINVAL.
