However, if the compound page spans multiple pageblocks
Although hugetlb pages spanning pageblocks are possible this shouldn't
matter in__test_page_isolated_in_pageblock because this function doesn't
really operate on pageblocks as the name suggests. It is simply
traversing all valid RAM ranges (see walk_system_ram_range).
As long as the hugepages don't span memory blocks/sections, you are
right. I have no experience with gigantic pages in this regard.
