Ok, so this patch doesn't remove any of the now unused
functionality I added to support the VFS based ioctl.

What I'm going to do with this is combine it with the initial
"introduce FS_IOC_FIEMAP" patch I wrote (including all it's
documentation!) as the first patch of the kernel side patch series
to introduced XFS_IOC_FIEMAPFS.

Cheers,

Dave.
