From 060c4f9c8cc871a96dfacdc9306101e8b9195805 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 21 Nov 2014 10:31:08 +0100 Subject: perf stat: Use perf_evsel__read_cb in read_counter Replacing __perf_evsel__read_on_cpu function with perf_evsel__read_cb function. The read_cb callback will be used later for global aggregation counter values as well.
