This seems like a separate issue which should better be debugged. Please open a new thread describing the problem and the state of the node.
Yes, in my view it should be evaluated separately too, because it's overall less concerning: __GFP_THISNODE there can only be set by the root user there. So it has a chance to be legitimate behavior there. Let's focus on solving the __GFP_THISNODE that any user in the system can set (not only root) and cause severe and unexpected swap storms or slowdowns to all other processes run by other users.
ls -l /sys/kernel/mm/hugepages/*/nr_hugepages
(and boot command line)
Thanks, Andrea
