I forgot to specify -DINVERSE_BIND is a noop unless -DHARD_BIND is specified too at the same time. -DINVERSE_BIND alone results in the default build without -D parameters. Now AutoNUMA has a bug and is real inverse bind too, I need to fix that. In the meantime this is possible: echo 0 >/sys/kernel/mm/autonuma/enabled run numa01_inverse echo 1 >/sys/kernel/mm/autonuma/enabled -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
