[RFC][PATCH 5/5] tracefs: Add directory /sys/kernel/tracing

2015-01-21 Thread Steven Rostedt 
From: "Steven Rostedt (Red Hat)" 

When tracefs is configured, have the directory /sys/kernel/tracing appear
just like /sys/kernel/debug appears when debugfs is configured.

This will give a consistent place for system admins to mount tracefs.
