It looks like node.h was modifed by #9304 to include tracing/trace_event.h but tracing/trace_event.h is missing from the tarballs (both the binary and header tarballs).

Why is trace_event.h included in node.h in the first place? I'd think node_internals.h is a better, more logical place for it.

[matthewloring]

It was included so the trace event macros could be used throughout core. If node_internals.h is a better place we can move it there. The contents of trace_event.h should be currently unused so it can be moved to a different place without any other refactoring.
