Well NAK, that is intentionally kept local to the amdgpu_ttm.c file.
This way we can make sure that we don't accidentally leak the structure

Thanks to explain that.
I thought those were left in the file accidentally.
Then fine to keep them in the file still.

What you could do is to move it to the beginning of the file.
