#     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")
