Hi, I cannot locate the definition of PageHead? It seems to have disappeared after v4.0? I can see it defined as a function here: https://elixir.bootlin.com/linux/v4.0/source/include/linux/page-flags.h#L401 But on the mainline (v5.1-rc2) I get: $ git grep ' PageHead' include/linux/page-flags.h:int PageHeadHuge(struct page *page); include/linux/page-flags.h: return PageHead(page); include/linux/page-flags.h: return PageHead(page) && test_bit(PG_double_map, &page[1].flags); mm/hugetlb.c: return PageHead(page) && PagePrivate(&page[1]); mm/hugetlb.c: * PageHeadHuge() only returns true for hugetlbfs head page, but not for mm/hugetlb.c:int PageHeadHuge(struct page *page_head) Clearly it is defined _somewhere_. Anyone any idea what brain dysfunction I am having right now? thanks, Tobin. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
