From f435887ec0c941b97301bd6ed1f3e4b5200df409 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 28 Feb 2019 15:00:24 +0200 Subject: perf db-export: Add calls parent_id to enable creation of call trees The call_path can be used to find the parent symbol for a call but not the exact parent call. To do that add parent_id to the call_return export. This enables the creation of a call tree from the exported data.
