mm: hugetlb: simplify per-node sysfs creation and removal
Patch series "simplify handling of per-node sysfs creation and removal",
v4.
This patch (of 2):
The following commit offload per-node sysfs creation and removal to a
kworker and did not say why it is needed. And it also said "I don't know
that this is absolutely required". It seems like the author was not sure
as well. Since it only complicates the code, this patch will revert the
changes to simplify the code.
39da08cb074c ("hugetlb: offload per node attribute registrations")
We could use memory hotplug notifier to do per-node sysfs creation and
removal instead of inserting those operations to node registration and
unregistration. Then, it can reduce the code coupling between node.c and
hugetlb.c. Also, it can simplify the code.
