The only reasonable explanation I can imagine for the weird stuff going on with "numa01_inverse" is that maybe it was compiled without -DHARD_BIND? 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
