From: Steven Rostedt rostedt@goodmis.org
The addition of recording both the function name and return address to the function graph tracer updated the selftest to check for "=-5" from "= -5". But this causes the test to fail on certain configs, as "= -5" is still a value that can be returned if function addresses are not enabled (older kernels).
Check for both "=-5" and " -5" as a success value.

Shuah, this update is only for changes in my tree, so you do not need to add it.
