tracing/fastboot: fix initcalls disposition in bootgraph.pl
Frederic Weisbecker [Sat, 4 Oct 2008 19:35:48 +0000 (21:35 +0200)]
When bootgraph.pl parses a file, it gives one row
for each initcall's pid. But only few of them will
be displayed => the longest.

This patch corrects it by giving only a rows for pids
which have initcalls that will be displayed.
