From a1a587073ccdc6ffae414259f65d0a94cadd0a72 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 17 Oct 2017 10:54:24 -0300 Subject: [PATCH] perf script: Use fprintf like printing uniformly We've been mixing print() with fprintf() style printing for a while, but now we need to use fprintf() like syntax uniformly as a preparatory patch for supporting printing to different files, one per event.
