Would calling this parent_dump (or something like that) be reasonable?

The relationship that this is for the URLRequestContext feels like a layering
violation (given that this code is in //net/base, which ideally would not depend
on net/url_request)

+      base::trace_event::MemoryAllocatorDump* url_request_context_dump) const;
