From fa7070a38676d660c0a71ab6981bfdca3b340ccd Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 30 Aug 2018 08:32:29 +0200 Subject: [PATCH] perf stat: Move csv_* to 'struct perf_stat_config' Move the static csv_* variables to 'struct perf_stat_config', so that it can be passed around and used outside the 'perf stat' command.
