Hm, the reason why I don't do that is for readability in
util/probe-event.c side. Passing params to the callee involves
 - export params struct (not be static)
 - callee has to extract required parameters from params.
 - it makes obscure that what parameters will be used in the method.

However, it seems that some of them would be better global configs
like symbol_conf. I'd like to suggest to introduce probe_conf global
config. Is it OK ?

Thank you,
