函数名称：Attempt to free all partial slabs on a node.* This is called from __kmem_cache_shutdown(). We must take list_lock* because sysfs file might still access partial list after the shutdowning.

函数原型：static void free_partial(struct kmem_cache *s, struct kmem_cache_node *n)

返回类型：void

参数：

类型参数名称
struct kmem_cache *s
struct kmem_cache_node *n
3704  LIST_HEAD(discard)
3707  BUG_ON(已禁止中断())
3708  spin_lock_irq( & list_lock)
3710  如果非 SLUB 则
3711  remove_partial(n, page)
3712  添加链表项
3713  否则
3714  list_slab_objects(s, page, "Objects remaining in %s on __kmem_cache_shutdown()")
3718  spin_unlock_irq( & list_lock)
3720  list_for_each_entry_safe - iterate over list of given type safe against removal of list entry*@pos: the type * to use as a loop cursor.*@n: another type * to use as temporary storage*@head: the head for your list.(page, h, & discard, slab_list)
