[PATCH 04/15] events: Update tools/lib/traceevent to work with perf

From: Frederic Weisbecker
Date: Wed Apr 25 2012 - 08:30:50 EST


From: Steven Rostedt <srostedt@xxxxxxxxxx>

Some of the util functions of libtraceevent.a conflict with perf,
such as die(), warning() and others. Move them into event-util.h
that is not included by the perf tools.

Also, as perf compiles with 'bool' the filter_arg->bool needs to
be renamed to filter_arg->boolean.
