is NULLVP, union node will have neither uppervp nor lowervp. This causes page fault trap. The union_removed_upper just remove union node from cache and it doesn't set uppervp to NULLVP. Since union node is removed from cache, it will not be referenced. The code that remove union node from cache was copied from union_inactive. |
