You can wake user processes,send them signals etc but ingeneral its not a good idea

The unix model is much more that the app does
while(1) { get_event(fd); switcH(event) { .. ... } }

The b_end_io callback can possibly be used, or Ben's asynchronosu callbacks, but that deals with kernel level completion.
