From 54f8f40384ab940e15585afde5c278c8e7726214 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 23 Dec 2015 02:07:01 +0900 Subject: [PATCH] perf top: Create the evlist sooner This is a preparation to support dynamic sort keys for tracepoint events. Dynamic sort keys can be created for specific fields in trace events so it needs the event information, so we need to pass the evlist to the sort routines, create it sooner so that the next patch can do that.
