Subject: tracing/fastboot: fix initcalls disposition in bootgraph.pl
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=07d1890420cce95c577736e4d67f70cbd39845fe;p=linux-beck.git

tracing/fastboot: fix initcalls disposition in bootgraph.pl

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.
