The kernel context (dev_priv->kernel_context) is unique in that it is not associated with any user filp - it is the only one with ctx->file_priv == NULL. This is a simpler test than comparing it against dev_priv->kernel_context which involves some pointer dancing. In checking that this is true, we notice that the gvt context is allocating itself a i915_hw_ppgtt it doesn't use and not flagging that its file_priv should be invalid.
