完善kobj_type结构体

1、实现kobj_type的release函数

#include<linux/module.h>
#include<linux/init.h>
#include<linux/kernel.h>
#include<linux/kobject.h>
#include<linux/slab.h>

static void dynamic_kobj_release(struct kobject *kobj);
struct my_kobject 
{
   
     struct kobject kobj;
     int value;
};
struct my_kobject  *my_kobject01;

static struct kobj_type mytype = {
   
.release= dynamic_kobj_release,
//.sysfs_ops= &kobj_sysfs_ops,
};


static void dynamic_kobj_release(struct kobject *kobj)
{
   
struct my_kobject* my_kobj = container_of(kobj, struct my_kobject, kobj);
     printk("kobject: (%p): %s\n", kobj, __func__);
kfree(my_kobj);
}

static int my_kobject_init(void)
{
   
     int ret;

     my_kobject01 = kzalloc(sizeof(struct my_kobject),GFP_KERNEL);
     ret = kobject_init_and_add(&my_kobject01->kobj,&mytype,NULL,"%s","my_kobject01");

     return 0;
}

static void
