[PATCH 7/7] tracing: remove funky whitespace in the trace code

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0007-tracing-remove-funky-whitespace-in-the-trace-code.patch --]
[-- Type: text/plain, Size: 14353 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: clean up

There existed a lot of <space><tab>'s in the tracing code. This
patch removes them.
