No, it doesn't work, CONFIG_HUGETLBFS can be enabled with CONFIG_NUMA=y
and CONFIG_SYSFS=n and that uses data structures from drivers/base/node.c
which doesn't get compiled with this patch.
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!
