[1,2] are small preps for the future that should change nothing functionally. [3] helps to reduce CPU usage on exit. We don't care about latency and CQEs when io_uring is going away, so checking it every HZ/20 should be enough Please, check the assumptions, because I hope that nobody expects ->iopoll() to do real work but not just completing.
