Subject: [PATCH 04/14] tracing: add private data field into struct ftrace_event_file

From: "zhangwei(Jovi)" <jovi.zhangwei@...wei.com>

Since modules can register own event_trace_ops tracing callback
functions now, so it's reasonable to allow modules have own
private data in struct ftrace_event_file.
