From 3cdfdf91fcc77cfc82592e2b5c2ab35abe819c41 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 25 Feb 2009 15:54:30 -0500 Subject: [PATCH] tracing: wrap arguments with PARAMS Peter Zijlstra warned that TPPROTO and TPARGS might become something other than a simple copy of itself. To prevent this from having side effects in the TRACE_FORMAT macro in tracepoint.h, we add a PARAMS() macro to be defined as just a wrapper.
