Description of problem: /bin/free has changed its output from f20 to f21. Why is that? There is missing line '-/+ buffers/cache:' Version-Release number of selected component (if applicable): procps-ng-3.3.10-4.fc21.x86_64 Actual results: total used free shared buff/cache available Mem: 15738 2070 6466 81 7201 13283 Swap: 7877 0 7877 Expected results: total used free shared buffers cached Mem: 1841 1737 103 95 84 313 -/+ buffers/cache: 1338 502 Swap: 2063 192 1871
Ahoj Branislave. The -/+ buffers/cache line lost sense with the recent modifications/additions and has been removed intentionally. The value reported as 'used' now excludes buffers and caches and therefore is equal to the previously reported '-' value and the value reported in the 'available' column is a correct/better replacement for the previously reported '+' value, that was marked as misleading and according to the kernel people, it was reinforcing a misconception that memory in the page cache can be considered free. If you have more questions, don't hesitate to ask. Otherwise I'll close this report as NOTABUG. Thanks, Jaromir.
Thank you for explanation.
