From a33fbd56ec83b5421090b4d8f2032f635e6a9488 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 Nov 2013 11:36:12 -0300 Subject: [PATCH] perf machine: Simplify synthesize_threads method Several tools (top, kvm) don't need to be called back to process each of the syntheiszed records, instead relying on the machine__process_event function to change the per machine data structures that represent threads and mmaps, so provide a way to ask for this common idiom.
