返回类型：void

参数：

类型参数名称
struct xarray *root
struct radix_tree_node *node
unsigned inttag
unsigned intoffset
1008  当node循环
1009  如果非tag_get(node, tag, offset)则返回
1011  tag_clear(node, tag, offset)
1012  如果Returns 1 if any slot in the node has this tag set.* Otherwise returns 0.则返回
1015  offset等于offset
1016  node等于parent
1020  如果root_tag_get(root, tag)则root_tag_clear(root, tag)
