The code is good (and can be applied from 3.7 onwards), but the commit
log needs work.
Since this patch is going to be backported this log needs to say why this
is done and make a note that this ioctl was never in the public api and was
only defined in a kernel-space header.
That last item needs to be in the commit log of patch 2/2 as well.
Also note in both patches that this ioctl is no longer in use anyway.
