Subject: Which one corresponds to ioctl in the file_operations struct in linux/fs.h?

Hi,

I have some driver code for older version of kernel. It refers to
ioctl in the file_operations struct. But this field is change in
kernel 3.0.0-13

I find the following in linux/fs.h

1566   long (*unlocked_ioctl) (struct file *, unsigned int, unsigned long);
1567   long (*compat_ioctl) (struct file *, unsigned int, unsigned long);

Does anybody know which one I should use in order to migrate the
driver code to the newer version of kernel? Thanks!
