SubjectIoctl warning for a partition
  Hello,

with your patches (commit 0bfc96cb in particular) to limit ioctl on
partitions we get warning:
dd: sending ioctl 80306d02 to a partition!
because dd checks whether given device is a tape (it's MTIOCGET ioctl).
It's easy enough to silence the warning the same way as
CDROM_GET_CAPABILITY since the ioctl is safe but it's not so simple for
32-bit userspace. MTIOCGET32 is defined only in fs/compat_ioctl.c so we
cannot easily add it to scsi_verify_blk_ioctl(). Any opinion how to cleanly
solve this? The only idea I had was to define compat structures and ioctl
numbers in a special header and use it both in fs/compat_ioctl.c and in
block/scsi_ioctl.c.
