In response to the question of what happens if the buffer never overflows. One will not get an interrupt if the buffer does not overflow. In this case, the event being monitored is very rare or the application being monitored has a very short execution time. In either case, the overhead of the interrupt is probably not a problem, and the user can either choose not to user in-kernel buffering for that event or simply ignore the events as being rare and insignificant.
If there are cases where it is important to have an user acknowledgement when the buffer never fills, people can use this forum to suggest a good solution for this.
