Description nemohan 2016-07-12 09:50:36 UTC 
in list.h file, sone functions like follow
static inline void __list_del(struct list_head * prev, struct list_head * next)
{
	next->prev = prev;
	prev->next = next;
}
if i set the prev =  NULL, or prev->next=NULL, the code does not check this situation, it will cause the kernel or application run to an unpredictable status
