radix_tree_delete

函数名称：adix_tree_delete_item - delete an item from a radix tree*@root: radix tree root*@index: index key*@item: expected item* Remove @item at @index from the radix tree rooted at @root.* Return: the deleted entry, or %NULL if it was not present

函数原型：void *radix_tree_delete_item(struct xarray *root, unsigned long index, void *item)

返回类型：void

参数：

类型	参数	名称

struct node = NULL

void __rcu * * slot = NULL

entry等于__radix_tree_lookup - lookup an item in a radix tree*@root: radix tree root*@index: index key*@nodep: returns node*@slotp: returns slot* Lookup and return the item at position @index in the radix* tree @root

1431

如果非slot则返回:NULL

1433

如果非entry且非is_idr(root)或node_tag_get(root, node, The IDR API does not expose the tagging functionality of the radix tree* to users. Use tag 0 to track whether a node has free space below it., get_slot_offset(node, slot))的值则返回:NULL

如果item且entry不等于item则返回:NULL
