- * This klist interface provides a couple of structures that wrap around
- * struct list_head to provide explicit list "head" (struct klist) and
- * list "node" (struct klist_node) objects. For struct klist, a spinlock
- * is included that protects access to the actual list itself. struct
- * klist_node provides a pointer to the klist that owns it and a kref
- * reference count that indicates the number of current users of that node
- * in the list.
+ * This file is released under the GPL v2.
*
- * The entire point is to provide an interface for iterating over a list
- * that is safe and allows for modification of the list during the
- * iteration (e.g. insertion and removal), including modification of the
- * current node on the list.

- * When deleting, klist_del() will simply decrement the reference count.
