解决方法：

# vi kernel/config.c

注释掉

// proc_iet_dir->owner = THIS_MODULE;

#make

解决方法：

# vi kernel/conn.c

注释掉

                case AF_INET6:
                //      snprintf(buf, sizeof(buf),

                        break;

#make

解决方法：

#vi kernel/file-io.o

修改代码如下：

        //res = sync_page_range(inode, mapping, ppos, count);
        res = filemap_write_and_wait_range(mapping, ppos, ppos + count - 1);
        if (res) {
                eprintk("I/O error: syncing pages failed: %d/n", res);
                return -EIO;

解决方法：

# vi kernel/block-io.c

修改代码如下：

//bdev = open_bdev_excl(path, flags, THIS_MODULE);

bdev = open_bdev_exclusive(path, flags, THIS_MODULE);
        if (IS_ERR(bdev)) {
                err = PTR_ERR(bdev);
                eprintk("Can't open device %s, error %d/n", path, err);
                bio_data->bdev = NULL;

-------------------------

//      if (bio_data->bdev)
//              close_bdev_excl(bio_data->bdev);
int flags = FMODE_READ | (LUReadonly(volume) ? 0 : FMODE_WRITE);

        if (bio_data->bdev)
                close_bdev_exclusive(bio_data->bdev, flags);

在文件开头的地方添加：

#include <linux/types.h>

#make

#make install
