(often seen as GFP_EXCL or as a semantic flag in allocators, or as VM_EXCLUSIVE in virtual memory areas) indicates that the memory should not be shared or aliased. In the labyrinth, an exclusive allocation is a locked door with a single key. define labyrinth void allocpagegfpatomic exclusive

The return type could imply that the AllocPage function does not return a value, but instead modifies the memory management data structures in place. // No free pages - "Sorry, the labyrinth
