数据结构中关于单链表的算法,将两个链表有序链合并成一个非递归有序的单链表,并不占用其他的存储空间,data structure of single-chain algorithm Listless and orderly of the two chains merged into a non- recursive and orderly single linked list, does not occupy other storage space

redis的C客户端hiredis不支持sharding，所以将ketama算法抽出来合并到hiredis里面了，增加了sharding功能。-the redis C client hiredis does not support sharding, so the ketama algorithm out to merge to hiredis inside, an increase of sharding function.
