From 8f28827a162fd1e8da4e96bed69b06d2606e8322 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Sun, 16 Aug 2009 22:05:48 +0200 Subject: perf tools: Librarize trace_event() helper Librarize trace_event() helper so that perf trace can use it too. Also clean up the debug.h includes a bit. It's not good to have it included in perf.h because it doesn't make it flexible against other headers it may need (headers that can also depend on perf.h and then create a recursive header dependency).
