/* Notes:
*
* We store bo pointer in drm_mm_node struct so we know which bo own a
* specific node. There is no protection on the pointer, thus to make
* sure things don't go berserk you have to access this pointer while
* holding the global lru lock and make sure anytime you free a node you
* reset the pointer to NULL.
