Move an allocation from old to new
void drm_mm_replace_node(struct drm_mm_node * old, struct drm_mm_node * new);
old
drm_mm_node to remove from the allocator
new
drm_mm_node which should inherit old's allocation
This is useful for when drivers embed the drm_mm_node structure and hence can't move allocations by reassigning pointers. It's a combination of remove and insert with the guarantee that the allocation start will match.
