Frederic Weisbecker 97aa105273 perf: Resurrect flat callchains ... Initialize the callchain radix tree root correctly. When we walk through the parents, we must stop after the root, but since it wasn't well initialized, its parent pointer was random. Also the number of hits was random because uninitialized, hence it was part of the callchain while the root doesn't contain anything. This fixes segfaults and percentages followed by empty callchains while running: perf report -g flat Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: 2.6.31.x-2.6.34.x <stable@kernel.org>		2010-07-08 06:20:15 +02:00
