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.
