This change is needed to pass the child vma (not the parent vma) to handle_mm_fault. We run handle_mm_fault on the child not on the parent, so the vma passed to handle_mm_fault has to be the one of the child obviously. It won't make a difference for the other users of the vma because both vma are basically the same.
