Reclaim pressure balance between anon and file pages is calculated
through a tuple of numerators and a shared denominator.
Exceptional cases that want to force-scan anon or file pages configure
the numerators and denominator such that one list is preferred, which
is not necessarily the most obvious way:
fraction[0] = 1;
fraction[1] = 0;
denominator = 1;
goto out;
Make this easier by making the force-scan cases explicit and use the
fractionals only in case they are calculated from reclaim history.
And bring the variable declarations/definitions in order.
