struct student

    char name[100];
    int num;
    struct list_head list;
};

struct student *pstudent;
struct student *tmp_student;

    int i = 0;

        printk("<0>student %d name: %s\n",tmp_student->num,tmp_student->name);
    }
    
    return 0;
}


void mylist_exit(void)
{    
    int i ;
    for(i=0;i<5;i++)
    {
        list_del(&(pstudent[i].list));
    }
    
    kfree(pstudent);
}

module_init(mylist_init);
module_exit(mylist_exit);


下面是Makefile

ifneq ($(KERNELRELEASE),)

obj-m := mylist.o

else
    
KDIR := /home/project/linux_prj/gq_prj/code_2/kernel-mini-4-3-1/linux-2.6.29
all:
    make -C $(KDIR) M=$(PWD) modules ARCH=arm CROSS_COMPILE=arm-linux-
clean:
    rm -f *.ko *.o *.mod.o *.mod.c *.symvers modul*

endif


makefile中KDIR是你的linux内核目录。
