From d2580c7a5b4e78bffda1e53cfd583e7a2c7383a5 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 13 Sep 2016 16:45:48 +0900 Subject: [PATCH] perf hist: Initialize hierarchy tree explicitly The hroot_in and hroot_out are roots of hierarchy trees of hist entries. But when a hist entry is initialized by copying existing template entry, it sometimes has non-empty tree and copies it incorrectly. This is a problem especially when an event group is used since it creates dummy entries from already-processed entries in other event members.
