Used memory was calculated as Total - Available. For newer kernels (3.14+), available memory is taken from /proc/meminfo, whereas for older kernels it is computed as free+buffered+cached. This commit changes that behavior. Available memory is still taken from /proc/meminfo, if available, but used memory is always computed as total-free-buffered-cached. This way, it matches the output of `free` for used memory (in the -/+ buffers/cache line) and other tools. Prior to this change, I'd see a reported used memory of 600MiB whereas free, htop and other tools would report a used memory of 1.8GiB. And adding used, cached, buffered and free memory would leave ~1.2GiB unaccounted for. |
