But, this patch looks to prevent compat_sys_ioctl() from handling other compatible ioctls that compat_ioctl_check_table function detects. For instance, fiemap (FS_IOC_FIEMAP) is handled via the function. I think we should only redirect own ioctl commands (i.e. NILFS_IOCTL_xxxx) to the nilfs_ioctl() call.
