Subject: [PATCH] perf trace: Filter out gnome-terminal* parent
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
