"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. hm, 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? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
