[RFC][PATCH 09/19] tracing: Rename ftrace_output functions to trace_output

From: Steven Rostedt
Date: Thu May 14 2015 - 11:24:43 EST


From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The ftrace_output_*() and ftrace_raw_output_*()
functions represent the trace_event code. Rename them to just trace_output
or trace_raw_output.
