From 733cd2fe197a0c696c54916f7395451c0da9b867 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 6 Sep 2013 22:40:11 +0300 Subject: perf evlist: Fix id pos in perf_evlist__open() Ensure the id_pos is correct when perf_evlist__open() is used. This fixes a problem introduced in 7556257 that broke 'perf kvm stat live' in that this tool wasn't updated to use the sample_type bits setting helpers.
