Subject: [PATCH] Add usdt probe to report activity function

Currently, if you want to catch any activity in your application, you
must install a callback. This works pretty well only when you profile
your own application. If you need to profile already existing target
applications without making any modifications to their code, you might
use bpf and usdt probes.
