Linux Kernel base tree Application Analysis LInux kernel base tree Application Analysis-- Lvyilong316 The base tree can be seen as a trie tree with binary strings as keywords. It is a multi-tree structure similar to a multi-layer index table, each intermediate node contains an array of pointers pointing to multiple nodes, and the leaf node contains pointers pointing to the actual object (because the object does not have a tree node structure, the parent node is considered as a leaf node ).
