Add a paragraph that explains that it may happen that the counters in /proc/meminfo do not add up to the overall memory usage.... that is, the sum may be lower because memory is allocated for other purposes that is not reported here, right?yes. Many direct page allocator users are not accounted in any of the existing counters.
