函数原型：static void radix_tree_free_nodes(struct radix_tree_node *node)

返回类型：void

参数：

类型参数名称
struct radix_tree_node *node
668  offset等于0
669  child等于entry_to_node(node)
671  循环
672  entry等于Dependency order vs. p above. (slots[offset])
673  如果Private 且shift则
674  child等于entry_to_node(entry)
675  offset等于0
676  继续下一循环
678  offset自加
679  当offset恒等于RADIX_TREE_MAP_SIZE循环
680  old等于child
681  offset等于offset加1
682  child等于parent
683  WARN_ON_ONCE(!链表为空)
684  radix_tree_node_free(old)
685  如果old恒等于entry_to_node(node)则返回
