Anyway, with the changes to print out warnings and still allow it for
root, this all looked safe and nice, so they are in my tree now. I
only noticed after applying them that you hadn't marked them with 'cc:
stable@kernel.org', so we should probably point Greg at them. They are
commits

   577ebb374c78 block: add and use scsi_blk_cmd_ioctl
   0bfc96cb7722 block: fail SCSI passthrough ioctls on partition devices
   ec8013beddd7 dm: do not forward ioctls from logical volumes to the
underlying device

in my tree now.

I'll tweak them myself for stable based on what you committed, so that 
they do not require your ENOTTY/ENOIOCTLCMD change (i.e. with the uglier 
v1 implementation).

Thanks very much.

Paolo, I've just done this for Debian's stable kernel based on 2.6.32.
I'll send them as a follow-up to this.

Ben.
