From ee76120e2d13a2d4eb0cc88da8a8e7f7909cc276 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 5 Oct 2012 14:02:14 +0900 Subject: [PATCH] perf trace: Explicitly enable system-wide mode if no option is given 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.
