I think the rule here should be a bit more nuanced. I think it is positively criminal to have an unnamed 'unsigned long' or 'bool' in a function prototype. But what extra information is communicated by adding 'root' after 'struct radix_tree_root *'? I know it's a root, you told me that with the structure name! Obviously sometimes it would be useful, for example if we had a function to move an entry from one radix tree to another, you might want to have 'struct radix_tree_root *old, struct radix_tree_root *new' as two of your parameters. > > int radix_tree_join(struct radix_tree_root *, unsigned long index, > > unsigned new_order, void *); > > Yes, the source file already omits some function prototype parameter names, > so these patches just follow that tradition.

Naming index and new_order is correct. But again, there's no useful information given by naming root. ��.n������g��� �a��� �&ޖ)���)��h���&������梷���� �Ǟ�m������)������^�����������v���O��zf������
