mm: fix mismerge of folio page flag manipulators
I had missed a semantic conflict between commit d389a4a81155 ("mm: Add folio flag manipulation functions") from the folio tree, and commit eac96c3efdb5 ("mm: filemap: check if THP has hwpoisoned subpage for PMD page fault") that added a new set of page flags. My build tests had too many options enabled, which hid this issue. But if you didn't have MEMORY_FAILURE or TRANSPARENT_HUGEPAGE enabled, you'd end up with build errors like this: include/linux/page-flags.h:806:29: error: macro "PAGEFLAG_FALSE" requires 2 arguments, but only 1 given 806 | PAGEFLAG_FALSE(HasHWPoisoned) | ^ due to the missing lowercase name used for folio function naming. Fixes: 49f8275c7d92 ("Merge tag 'folio-5.16' of git://git.infradead.org/users/willy/pagecache") Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Reported-by: Yang Shi <shy828301@gmail.com> Cc: Matthew Wilcox <willy@infradead.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
