Naoya Horiguchi 70fb727d09 kpageflags: fix wrong KPF_THP on non-huge compound pages ... commit 7a71932d56 upstream. KPF_THP can be set on non-huge compound pages (like slab pages or pages allocated by drivers with __GFP_COMP) because PageTransCompound only checks PG_head and PG_tail. Obviously this is a bug and breaks user space applications which look for thp via /proc/kpageflags. This patch rules out setting KPF_THP wrongly by additionally checking PageLRU on the head pages.
