新手求助

大家好啊，我是linux方面的新手，由于毕业设计做的是linux设备驱动程序研究，才开始接触它的，总的来说对它是一无所知。现在正在调试网上一个现成的字符设备驱动程序，可发现其中有很多编译错误，可不知从何开始调试，望大家能够帮帮我。因为我对gcc还是很陌生，谢谢啦！源代码如下：
#include <linux/fs.h>
#include <linux/mm.h>
#include <linux/errno.h>
#include <asm/segment.h>
unsigned int test_major = 0;

static int read_test(struct inode *node，struct file *file，
char *buf，int count)
static int write_tibet(struct inode *inode，struct file *file，
const char *buf，int count)
static int open_tibet(struct inode *inode，struct file *file )
static void release_tibet(struct inode *inode，struct file *file )
static void release_tibet(struct inode *inode，struct file *file )

struct file_operations test_fops = {
NULL，
read_test，
write_test，
NULL， /* test_readdir */
NULL，
NULL， /* test_ioctl */
NULL， /* test_mmap */
open_test，
release_test， NULL， /* test_fsync */
NULL， /* test_fasync */
/* nothing more， fill with NULLs */
};  
static int read_test(struct inode *node，struct file *file，
char *buf，int count)
{
int left;
if (verify_area(VERIFY_WRITE，buf，count) == -EFAULT )
return -EFAULT;
for(left = count ; left > 0 ; left--)
{
__put_user(1，buf，1);
buf++;
}
return count;
}
static int write_tibet(struct inode *inode，struct file *file，
const char *buf，int count)
{
return count;
}
static int open_tibet(struct inode *inode，struct file *file )
{
MOD_INC_USE_COUNT;
return 0;
}
static void release_tibet(struct inode *inode，struct file *file )
{
MOD_DEC_USE_COUNT;
}

int init_module(void)
{
int result;
result = register_chrdev(0， "test"， &test_fops);
if (result < 0) {
printk(KERN_INFO "test: can't get major number\n");
return result;
}
if (test_major == 0) test_major = result; /* dynamic */
return 0;
}
void cleanup_module(void)
{
unregister_chrdev(test_major， "test");
}  

编译结果如下：
