error:unknown field 'ioctl' specified in initializer

在linux-2.6.36内核上加载编译驱动时,出现

 error:unknown field 'ioctl' specified in initializer

原因是:在2.6.36内核上file_operations发生了重大的改变:

原先的

  int (*ioctl)(struct inode*, struct file*, unsigned int, unsigned long);

被改为了       

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

因而在实际驱动中,我们需要将原先的写的ioctl函数头给改成下面的unlocked_ioctl,在file_operations结构体的填充中也是一样。
