Hi Srikar,

Sorry to ask this after agreeing :P
Initially, I thought this point is right. But after thinking more on this, it seems wrong to me. Ex a python SDT probe:
Provider: python Name: function__entry Location: 0x0000000000140de4, Base: 0x00000000001ddfb0, Semaphore: 0x0000000000268320
Here, "Semaphore" field is what we are referring to as reference counter. Basically reference counter's job is to gate invocation of uprobe and thus ref_ctr_offset becomes a uprobe property, not the consumer property. No? Am I missing anything?
Thanks, Ravi
