From 1971f59f1a1e0e7f3efc25ce0597505626d9f7ed Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 21 Nov 2014 10:31:10 +0100 Subject: [PATCH] perf stat: Use read_counter in read_counter_aggr Use the read_counter function as the values retrieval function for aggr counter values thus eliminating the use of __perf_evsel__read function.
