From fed5af61dc0d9402d26e7fb8fb9731a60a8e05ca Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 7 Jan 2010 19:59:38 -0200 Subject: perf buildid-list: No need to process the header sections again MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As it is already processed by: perf_session__new perf_session__open perf_session__read This was harmless, because we use dsos__findnew, that would already find it, but is unnecessary work and removing it makes builtin-buildid-list.c even shorter.
