(kgdb) list *vm_object_terminate+0x1d8
0xffffffff80b5cc58 is in vm_object_terminate (/usr/src/sys/vm/vm_object.c:767).

763             /*
764              * Let the pager know object is dead.
765              */
766             vm_pager_deallocate(object);
767             VM_OBJECT_UNLOCK(object);
768 
769             vm_object_destroy(object);
