gee. "available" implies "available for you to allocate". It has the
same problem as "free".

And "buffer" shouldn't be there - that's a reflection of the fact
that buffer_head payloads are not allocated from highmem. An archaic
irrelevant thing.

Seriously, first let's write down the descriptions of what these
functions *do*. Then choose nice names which abbreviate that.


static unsigned int nr_free_zone_pages(int offset)
unsigned int sum = 0;
return sum;

How long will it be until these things start exploding from
sums-of-zones which exceed 16TB?
