Date: Thu, 18 Jun 2015 23:48:55 +0200 From: Jiri Olsa <jolsa@...nel.org> To: Arnaldo Carvalho de Melo <acme@...nel.org> Cc: lkml <linux-kernel@...r.kernel.org>, Adrian Hunter <adrian.hunter@...el.com>, Andi Kleen <ak@...ux.intel.com>, David Ahern <dsahern@...il.com>, Ingo Molnar <mingo@...nel.org>, Namhyung Kim <namhyung@...nel.org>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, Stephane Eranian <eranian@...gle.com> Subject: [PATCH 16/26] perf stat: Introduce perf_evsel__alloc_stats function Move all stat allocation logic related to stat object under single function. This way we can use it separately for stat object out of evlist object.
