From 93d5731dcb5b8cb7fa56ee11a5891f10c96c2a45 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 21 Mar 2014 17:57:01 -0300 Subject: perf tools: Allocate thread map_groups's dynamically Moving towards sharing map groups within a process threads. Because of this we need the map groups to be dynamically allocated. No other functional change is intended in here. Based on a patch by Jiri Olsa, but this time _just_ making the conversion from statically allocating thread->mg to turning it into a pointer and instead of initializing it at thread's constructor, introduce a constructor/destructor for the map_groups class and call at thread creation time. Later we will introduce the get/put methods when we move to sharing those map_groups, when the get/put refcounting semantics will be needed.
