From 8ad94c6052649a8e32120b464eefa0ffd8f2f04f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 3 Feb 2010 16:52:03 -0200 Subject: [PATCH] perf probe: Don't use a perf_session instance just to resolve symbols MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit With the recent modifications done to untie the session and symbol layers, 'perf probe' now can use just the symbols layer.
