Note that we have two different dev_ifsioc() defintions, which is a little weird. But the net/socket.c one does indeed seem superflous as there is no point in doing the compat_alloc_user_space / copy_in_user as far as I can tell. compat_ifreq differs from ifreq in the size of ifru_data, but it seems none of these ioctls actually use it. A better changelog would be nice, though.
