From bfa346ad6b4dd88c19f560b5b0527d93fa05833b Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 28 Feb 2012 10:49:38 -0800 Subject: gadget: Use vsprintf extention %pf with builtin_return_address Emit the function name not the address when possible. builtin_return_address() gives an address. When building a kernel with CONFIG_KALLSYMS, emit the actual function name not the address.
