From: "Aneesh Kumar K.V" <redacted> Add the hugetlb cgroup pointer to 3rd page lru.next. This limit the usage to hugetlb cgroup to only hugepages with 3 or more normal pages. I guess that is an acceptable limitation.

That should be if (compound_order(page) < 2) ? I will send an updated patchset with this fix and other review changes. -aneesh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
