bpf load and unload as just another tracepoint to throw into a set of
events that are monitored. As mentioned before auditing the loads and
unloads is one example.

And that brings up another comment: Why are you adding a PERF_RECORD_*
rather than a tracepoint? From what I can see the PERF_RECORD_BPF_EVENT
definition does not include the who is loading / unloading a bpf
program. That is important information as well.
