perf kmem: Print big numbers using thousands' group
Like perf stat, this makes easy to read the numbers on stat like below: # perf kmem stat SUMMARY ======= Total bytes requested: 9,770,900 Total bytes allocated: 9,782,712 Total bytes wasted on internal fragmentation: 11,812 Internal fragmentation: 0.120744% Cross CPU allocations: 74/152,819 Suggested-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Joonsoo Kim <js1304@gmail.com> Cc: Minchan Kim <minchan@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1427092244-22764-2-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
