Hi all,

After merging the folio tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

mm/readahead.c: In function 'read_cache_pages_invalidate_page':
mm/readahead.c:54:17: error: implicit declaration of function 'do_invalidatepage'; did you mean 'd_invalidate'? [-Werror=implicit-function-declaration]
   54 |                 do_invalidatepage(page, 0, PAGE_SIZE);
      |                 ^~~~~~~~~~~~~~~~~
      |                 d_invalidate

Caused by commit

  f1fdabbaae8e ("fs: Turn do_invalidatepage() into folio_invalidate()")

I have used the folio tree from next-20220310 for today.
