They return true when CONFIG_TRACEPOINTS is configured in and the
tracepoint is enabled, and false otherwise.

This implementation is what you proposed before. Please refer below
link and source.

That was a year ago, how am I suppose to remember ;-)

I think you are smart enough to remember. :)
I will add it on commit description on next spin.

There is header file dependency problem between mm.h and tracepoint.h.
page_ref.h should be included in mm.h and tracepoint.h cannot
be included in this case.

Ah, OK, I forgot about that. I'll take another look at it again.

A lot happened since then, that's all a fog to me.

Okay. Please let me know result of another look.

Thanks.
