From b424eba27160dd19577896d4520b8eebabed919f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 9 Nov 2011 13:24:25 -0200 Subject: perf session: Move threads to struct machine The 'machine' abstraction was introduced with 'perf kvm' where we could have samples for the host and multiple guests, but at the time we ended up keeping the list of all machines threads all in session->host_machine. Move the threads rb_tree to struct machine to separate the namespaces.

Next steps will remove the 'session' pointer, that in most cases is not needed. Then we can rename perf_event_ops to 'perf_tool' that better describes this class hierarchy.
