Thanks. In next version we will introduce a new function which do oppsite

perf_event_release_kernel() in perf/event/core.c, then fetch the event
before fdput.
perf_event_get() as proposed, with the addition of the refcount
increment inside the fdget/fdput() is fine.
Note that the _get() name already implies a refcount increment.
OK, you'll see it in v2.
Thank you.
