From 45694aa7702bc44d538a3bcb51bb2bb96cf190c0 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 28 Nov 2011 08:30:20 -0200 Subject: [PATCH] perf tools: Rename perf_event_ops to perf_tool To better reflect that it became the base class for all tools, that must be in each tool struct and where common stuff will be put.
