Hello friends,
Can anyone please tell me what the not_a_pt: label in do_mmu_update used for?

default:
not_a_pt:
                    {
                        if ( unlikely(!get_page_type(page, PGT_writable_page)) )
                                    break;

                        perfc_incr(writable_mmu_updates);
                        okay = paging_write_guest_entry(v, va, req.val, _mfn(mfn));
   
                        put_page_type(page);
                    }
                    break;
               

Regards,
Furquan
