io_uring_get_events - Flush outstanding requests to CQE ring

       The io_uring_get_events(3) function runs outstanding work and flushes completion events to the CQE ring.

       There  can be events needing to be flushed if the ring was full and had overflowed.  Alternatively if the
       ring was setup with the  IORING_SETUP_DEFER_TASKRUN  flag  then  this  will  process  outstanding  tasks,
       possibly resulting in more CQEs.
