I wouldn't argue further on that if you insist. However, I still want to relax the constraint somewhat by abandoning the no internal process constraint when only threaded controllers (non-resource domains) are enabled even when thread mode has not been explicitly enabled. It is a modified version my second alternative. Now the question is which controllers are considered to be resource domains. I think memory and blkio are in the list. What else do you think should be considered resource domains? Cheers, Longman any of the resource domains (!threaded) controllers are enabled. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
