From 99471c967a00c875bb5d61f377d4267904545499 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 25 Oct 2015 15:51:20 +0100 Subject: perf thread_map: Add thread_map event sythesize function Introduce the perf_event__synthesize_thread_map2 function to synthesize struct thread_map. The perf_event__synthesize_thread_map name is already taken for synthesizing the complete threads data (comm/mmap/fork).
