ok, agreed.

Btw, I wonder why these common ioctl's aren't handled in a common
file, as is already done with BLKROSET and BLKROGET via the RO_IOCTLS
macro. For instance, code for BLKFLSBUF, BLKRAGET and BLKRASET is
similar for all block devices, except for taking advantage of local
macros where available.

:-)

What you're seeing here is the new HDIO_GETGEO ioctl in action :-)
(As floppy disks don't have partition tables, it's not really useful
for fdisk, but might be useful for Lilo in the future.)
