David Rientjes 69ed779a14 mm, hugetlb: schedule when potentially allocating many hugepages ... A few hugetlb allocators loop while calling the page allocator and can potentially prevent rescheduling if the page allocator slowpath is not utilized. Conditionally schedule when large numbers of hugepages can be allocated. Anshuman: "Fixes a task which was getting hung while writing like 10000 hugepages (16MB on POWER8) into /proc/sys/vm/nr_hugepages."
