Date: Wed, 10 Jul 2019 11:58:03 +0300 From: Adrian Hunter <adrian.hunter@...el.com> To: Arnaldo Carvalho de Melo <acme@...nel.org> Cc: Jiri Olsa <jolsa@...hat.com>, linux-kernel@...r.kernel.org Subject: [PATCH 14/21] perf scripts python: export-to-postgresql.py: Add has_calls column to comms table Now that a thread's current comm is exported, it shows up in the call graph and call tree even if it has no calls. That can happen because the calls are recorded against the main thread's initial comm. Add a table column to make it easy for the exported-sql-viewer.py script to select only comms with calls.
