From df1d6856eaa7ec9ad1e670685b370f3e66326079 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 21 Jul 2019 13:23:48 +0200 Subject: [PATCH] perf stat: Move loaded out of struct perf_counts_values Because we will make struct perf_counts_values public in following patches and 'loaded' is implementation related. No functional change is expected.
