From 983874d173568f584a5988888645725496c09f24 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 3 Jan 2014 17:25:49 -0300 Subject: perf evlist: Auto unmap on destructor Removing further boilerplate after making sure perf_evlist__munmap can be called multiple times for the same evlist.
