Subject[RFC][PATCH 1/2] [PATCH 1/2] tracing: Rename trace_printk to ftrace_printk
From: Steven Rostedt <srostedt@redhat.com>

In order to make a bit more generic trace_printk(), this patch
simply renames the trace_printk() macro to its original ftrace_printk()
name, since it only writes into the ftrace ring buffer.
