From 6e344a952dcfa45b8bfef8eaf8423ab73c5adaf2 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 25 Apr 2014 12:28:13 +0900 Subject: perf tests: Factor out fake_setup_machine() The fake_setup_machine() is for setting up a environment for testing various hists operations. As it'll be used for other test cases it'd better factoring it out.
