I know breaking user-interface is a bad thing across releases. But in this particular case, it's probably ok (since fair-group scheduling is a brand new feature in Linux)? If we have that option of breaking API between 2.6.23 and 2.6.24 for fair-group scheduler, then we are in a much more flexible position. For 2.6.23, I can send a user-id based interface for fair-group scheduler (with some /proc interface to tune group nice value). For 2.6.24, this user-id interface will be removed and we will instead switch to container based interface. Fair-user scheduling will continue to work, its just that users will have to use a daemon (sources sent in previous mail) to enable it on top of container-based interface.
