Self-NACK.
Everything seems to work, including the additional cleanupe I sent, but:

this can't help perf.
I never used it before so I naively thought that it writes to tracing/uprobe_events and does perf_event_open(id) in the single session, but this is not true.
I'll try to do something else. It seems that we can use TRACE_REG_PERF_OPEN rather than TRACE_REG_PERF_REGISTER and exploit event->ctx->task->mm to implement the pre-filtering...
Oleg.
