Muchun Song b958d4d08f 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. 39da08cb07 ("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.
