Linux General linked list instances and linuxlist instances

The linked list used in the Linux kernel is reusable without repeated wheel creation. it is easy to think of a linked list using the following method: struct list {strucu list * next, * prev; int priv_data ;}; data is stored in the node of the linked list and moved by next and prev to access the priv_data on each node. the problem is that the Code is almost reusable, and different data storage requires a variety of lists. in linux kernel, a linked list containing data outside the node can solve this problem. struct list_head {struct list_head * prev, * next;}; struct list_data {struct list_head head; int priv_data ;}; the list_data data structure only needs to contain a linked list structure list_head to use the features of the linked list.
