Windows内核链表删除某一结点

Question

typedef struct _List
{
    LIST_ENTRY ListEntry;
    ULONG number;
}List,*PList;
LIST_ENTRY ListHead;

VOID dellist() 
{
    PList plist;
    PLIST_ENTRY temp=NULL;
    if (IsListEmpty(&ListHead))
    {
        DbgPrint("Link is null\n");
        return;
    }
    plist = (PList)ExAllocatePool(PagedPool, sizeof(List));
    plist->number = 2;
    temp = ListHead.Flink;
    while (temp!=&ListHead)
    {
        if (plist->number== ((PList)temp)->number)
        {
            //DbgPrint("found 2\n");
            
            ExFreePool(temp);
        }
        DbgPrint("%d", ((PList)temp)->number);
        temp = temp->Flink;
    }
    return;
}

全局链表ListHead中存储着数字1-10，在while语句里找到匹配ListHead里有2的时候，我想把2的内容给删除掉。
