I think this is fantastic! Yes please!
Can I add one more test case?
/**
* radix_tree_lookup_slot - lookup a slot in a radix tree
* @root: radix tree root
* @index: index key

* Returns: the slot corresponding to the position @index in the

void __rcu **radix_tree_lookup_slot(const struct radix_tree_root *root,
unsigned long index)
{ }
(we used to have a problem with multiple '*' in the return type, and
we've also had problems with adornments like __rcu)
