I have written a character device driver. In the ioctl function , i want to use a function called ext2_get_inode() which has been defined in the file /usr/src/linux-2.6.11/fs/ext2/inode.c. I am not able to use this function in my device driver.
Following is the code for my device driver :
int my_release(struct inode *inode,struct file *filep)
int my_ioctl(struct inode *inode,struct file *file,unsigned int cmd,unsigned long arg)
printk(KERN_ALERT "\nThe reserved number is %d.",t1);
It is giving me a lot of warnings of function undefined when i use the make command.
But if i use insmod, it is giving me a lot of errors for the same files.
Can anyone help me as to how to use this function in that particular file???
