From 3e2be2da8f76ef5b2e8e59c3dc8acd24640b4af4 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 3 Jan 2014 15:03:26 -0300 Subject: [PATCH] perf record: Remove old evsel_list usage To be consistent with other places, use just 'evlist' for the evsel list variable, and since we have it in 'struct record', use it directly from there.
