From 9c105fbc94a67ea5943d309d9a78ca669e0ddc61 Mon Sep 17 00:00:00 2001 From: Dongsheng Yang Date: Wed, 4 Dec 2013 17:56:40 -0500 Subject: [PATCH] perf target: Move the checking of which map function to call into function. Check for cpu_map__dummy_new() or cpu_map__new() to be called in perf_evlist__create_maps() is more complicated. This patch moves the checking work into target.h, combining two conditions and making perf_evlist__create_maps() more readable.
