The _get name does not really correlate with what is happening -- ie.,
allocate a new event and add it to the queue. There is no reference taken
either.

ook.. so how about ordered_events_alloc ordered_events_free

+static void
+ordered_event_put(struct ordered_events_queue *q, struct ordered_event *iter)

Similarly here with the _put. In this case the function is moving the event
from one list to another. And how about something else for the name besides
iter -- oe, or oevent?

how about 'event' ?

Already a heavily used keyword in perf, that's why I was thinking oe or oevent -- besides it is a struct ordered_event not an event.

The bigger thing to me with this patch is the _get/_put names.
