Building for Linux Kernel after version 2.6.36
在2.6.36之後的版本，原先使用的IOCTL已經完全的被移除掉，而在這之後的版本IOCTL可以看到
long (*unlocked_ioctl) (struct file *,
unsigned int, unsigned long);
long (*compat_ioctl) (struct file *, unsigned int, unsigned long);
其中ioctl改成使用unlocked_ioctl，如果User Space是32位元，Kernel是64位元，則使用compat_ioctl
範例
| 2.6.35以前使用方式 |
| static
struct file_operations MyDriver_fops = { .owner = THIS_MODULE, .llseek = no_llseek, .read = MyDriver_read, .write = MyDriver_write, .ioctl = MyDriver_ioctl, .open = MyDriver_open, .release = MyDriver_release }; |
