I prefer getting the error on io_getevents(). The code that handles the
output of io_getevents() already has to handle per-operation errors.
The only thing user space can reasonably do with errors returned by
io_submit() is to retry or assert. Anything else would duplicate logic
that already has to be in and is better handled by the code that handles
the output io_getevents().
io_submit() should only return errors in cases where the caller is
obviously buggy/malicious or in cases where it is not possible to
generate an event.
