kvmi_tracked_gfn does not exist yet. More in general, this comment says why you are calling this here, but it says nothing about the split of responsibility between kvmi_end_introspection and kvmi_release. Please add a comment for this as soon as you add kvmi_end_introspection (which according to my earlier review should be patch 1).
