[Mutex::new] is a const function, too, so it can be used in statics.

Now we can test it by adding some frame allocations:
|
||||
|

println!("{:?}", frame_allocator.allocate_frame())
|

println!("{:?}", frame_allocator.allocate_frame());
|

```
|

You will see that the frame number starts at `0` and increases steadily, but the kernel and Multiboot frames are left out (you need to allocate many frames to see this since the kernel starts at frame 256).
