From 1fcd03946b52b8a57a6692fedd4406b45baedfe6 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Tue, 5 Dec 2017 22:03:04 +0800 Subject: perf stat: Update per-thread shadow stats The functions perf_stat__update_shadow_stats() is called to update the shadow stats on a set of static variables. But the static variables are the limitations to be extended to support per-thread shadow stats. This patch lets the perf_stat__update_shadow_stats() support to update the shadow stats on a input parameter 'st' and uses update_runtime_stat() to update the stats. It will not directly update the static variables as before.
