Creating a list node

To create new nodes, just create our data struct instances and initialize their embedded list_head field. Using the car example will give the following:

struct car *blackcar = kzalloc(sizeof(struct car), GFP_KERNEL); 
 
/* non static initialization, since it is the embedded list field*/ 
INIT_LIST_HEAD(&blackcar->list); 

As we said earlier, use INIT_LIST_HEAD, which is a dynamically allocated list and usually part of another structure.
