From bdef3b02ceeb97f5f67fcfa6dff13c4e70b34fb7 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 14 Apr 2010 20:05:17 +0200 Subject: [PATCH] perf: Always record tracepoints raw samples from perf record Trace events are mostly used for tracing rather than simple counting. Don't bother anymore with adding -R when using them, just record raw samples of trace events every time.
