No, it is not "more clear", the two defines are not the same thing, they
do different things.  If they were just identical, we would not need
them both :)

So please be very explicit as to _why_ you want to change this, and show
how you have verified that changing this is the correct thing to do, and
how you tested.  Because the user-visible change can be quite different
with this type of kernel change.

thanks,
