[PATCH 1/4] tracing: Use outer () on __get_str() definition

From: Daniel Bristot de Oliveira
Date: Fri Jul 01 2016 - 19:44:54 EST


__get_str(str)'s definition includes a (char *) operator
overloading that is not protected with outer ().

This patch adds () around __get_str()'s definition, enabling
some code cleanup.
