        Those functions are currently ineffective. This is a preparation patch
        for stream IO implementation.
    
    OK for master.
    Thanks.

While implementing `forget', I realized it is not clear what are the
values returned by ios_flush, and the internal interface
ios_dev_if->flush.

I am assuming that it returns IOS_OK in case of success, and !=IOS_OK in
case of error.  It would be good to state that explicitly in the code.
