NAK, sorry.

1) it does not belong in ring_buffer.h. The ring buffer.h is for the
ring buffer only, and is agnostic to other tracing code.

2) trace_prink() and friends needs to be with printk. It is not used
much in the delivered kernel but it is used often in development. That
is, we purposely made it so it is not needed to add a header file to
everyplace you use trace_prink(). When debugging a problem,
trace_printk() needs to be as convenient as adding printk(), and by
needing to find "what header includes trace_printk()" will become an
overwhelming inconvenience.
