If you do not like this, you can just throw it away. <linux/radix-tree.h> includes <linux/radix-tree-root.h>. You do not need to include both. -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
