Date: Mon, 8 Oct 2012 19:32:27 -0300 From: Arnaldo Carvalho de Melo <acme@...radead.org> To: Ingo Molnar <mingo@...nel.org> Cc: linux-kernel@...r.kernel.org, Namhyung Kim <namhyung.kim@....com>, Namhyung Kim <namhyung@...nel.org>, Paul Mackerras <paulus@...ba.org>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, Arnaldo Carvalho de Melo <acme@...hat.com> Subject: [PATCH 02/25] perf trace: Explicitly enable system-wide mode if no option is given From: Namhyung Kim <namhyung.kim@....com> When no target cpu/user/task option is given, perf trace will do its job system wide for all online cpus. Make it explicit to reduce possible confusion when reading code. No functional changes intended.
