Subject[PATCH 18/43] perf trace: Filter out gnome-terminal* parent
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Just like it does with 'sshd', to reduce the feedback loop when doing
system wide tracing on on a gnome GUI.

Need to figure out how to auto-filter the calls to other UI components
tho.
