From f66a889dbc96dd342c87232d74f0956076707746 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 18 Aug 2014 17:25:59 -0300 Subject: perf evlist: Introduce poll method for common code idiom Since we have access two evlist members in all these poll calls, provide a helper. This will also help to make the patch introducing the pollfd class more clear, as the evlist specific uses will be hiden away perf_evlist__poll().
