For example, by measuring how much of that "bloat" is actually
experienced (e.g., in the form of presence in cache or additional time
taken.) when that instrumentation is turned off vs. on.  That should
sound familiar, as this is the sort of data that you outlined (but I
don't recall whether you actually provided numbers/recipes) when
describing the "dyn-ftrace" nop-padding work.
