No, it doesn't work, CONFIG_HUGETLBFS can be enabled with CONFIG_NUMA=y

So, you mean with CONFIG_NUMA=y&& CONFIG_SYSFS=n&& CONFIG_HUGETLBFS=y
we still get compile error?
Which data structures are used by hugetlbfs?
node_states[], which is revealed at link time if you tried to compile your
patch. It's obvious that we don't want to add per-node hugetlbfs
attributes to sysfs directories if sysfs is disabled, so you need to
modify the hugetlbfs code as well.
Makes sense. Thanks!
