Currently, in anon_vma_clone(), src vma's anon_vma is assigned to active_anon_vma and is used when unlocking anon_vma after linking new AVCs. However, the anon_vma is locked using src->anon_vma, instead of active_anon_vma, making the lock and unlock target inconsistent. Use active_anon_vma for both locking and unlocking.
