"klist" "k" stand for what ?

[galcon zhao]

 HI ALL:

    I am reading kernel source code ,but  I have a question.

    struct klist {
        spinlock_t k_lock;
        struct list_head k_list;
        void (*get)(struct klist_node *);
        void (*put)(struct klist_node *);
    } __attribute__ ((aligned (sizeof(void *))));
    "klist"    "k"  stand for what  ?

    I think "k" is "key",  Is it right?
