From cb0b29e0861659c9eef9664772cd7e845ba1104a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 2 Aug 2012 11:42:57 -0300 Subject: [PATCH] perf evlist: Introduce perf_evlist__parse_sample That is a more compact form of perf_session__parse_sample and to support multiple evlists per perf_session is the way to go anyway.
