From 5c6974f49832a55edc9ca744323778947c104ca0 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 2 Aug 2013 17:41:09 -0700 Subject: [PATCH] perf evlist: Remove obsolete dummy execve Minor cleanup. The dummy execve to pre-resolve the PLT is obsolete since "enable_on_execve" was added. The counters are only running after the execve anyways. So just remove it.
