yep.

Furthermore note that latency_trace is a legacy format which i
think we'll deprecate - in fact see the patch below. The primary
format that people use is /debug/tracing/trace.

All the pretty-printing patches that Andrew has seen and
complained about affect /debug/tracing/trace, not
/debug/tracing/latency_trace.
