Err,

are you thinking of something in TRACE_EVENT() that sets
perf_event_attr.persistent to 1?

Btw, the more important question is are we going to need persistent
events that much so that a generic approach is warranted? I guess maybe
the black box events recording deal would be another user..

IOW, please elaborate :)

Thanks.
