Subject: Re: [PATCH] tracing: don't macro-expand arguments before stringification in TP_printk

Bah, just found 0462b5664b (ftrace: Output REC->var instead of
__entry->var for trace format). There's some magic here I don't
understand, but I'm wondering if '__entry' wouldn't do just as well as
'REC' for the tools that try to parse these strings.
