Commit f1e61557 ("mm: pack compound_dtor and compound_order into one word in struct page") changed compound_dtor from a pointer to an array index in order to pack it. To check if page has the hugeltbfs compound_dtor, we can just compare the index directly without fetching the function pointer. Said commit did that with PageHuge() and we can do the same with PageHeadHuge() to make the code a bit smaller and faster. Signed-off-by:
