314  如果Navigate through the internal tree looking for the closest node to the key.不等于assoc_array_walk_found_terminal_node则返回:NULL
318  node等于 Node in which leaf might be found
323  以slot小于Number of slots per node 循环
324  ptr等于READ_ONCE(slots[slot])
325  如果ptr且assoc_array_ptr_is_leaf(ptr)则
330  leaf等于assoc_array_ptr_to_leaf(ptr)
331  如果compare_object(leaf, index_key)则返回:leaf
336  返回:NULL

名称描述
find_key_to_updateSearch the given keyring for a key that might be updated.* The caller must guarantee that the keyring is a keyring and that the* permission is granted to modify the keyring as no check is made here. The
search_keyringSearch inside a keyring for a key. We can search by walking to it* directly based on its index-key or we can iterate over the entire* tree looking for it, based on the match function.
