Actually, Li if you don't mind, I'm going to break this up into separate
patches. Each of the above "topics" really should be a separate patch.
It makes bisecting and such nicer if for some strange reason this patch
became the cause.

Actually it does more than I described:
- indent some lines
- fix a typo in comment
- remove trace_field_cont
- remove tracer_switch_ops
- remove @stats from struct tracer
- move 2 macros to trace_events_filter.c
I'm not sure it worths breaking into several patches, since each of them
is trivial.
But I won't mind if you break this up, or if you want me to do
this.

Yeah I already broke it up and sent it out. Some could go together, but
I did not like moving code mixed with other cleanups.
