From dac74940289f350c2590bec92737833bad608541 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 5 Feb 2009 01:13:38 -0500 Subject: [PATCH] trace: code style clean up Ingo Molnar suggested using goto logic to keep the indentation down and to be able to remove the nasty line breaks. This actually makes the code a bit more readable.
