This patch series does most of the page->folio conversions needed in
nilfs2. I haven't done the work to support large folios in nilfs2;
I don't know if that conversion will be worth the effort. There are
still a few page uses left, but the infrastructure isn't quite there to
get rid of them yet.
Arguably, this is two separate series; the first takes care of the file
paths and the second takes care of directories. I've tried my best to
include large folio support in the directory code because it'll be needed
for large block size devices. It also tries to stay as close as possible
to the current ext2 code (so it also includes kmap_local support).
These patches are only compile-tested. xfstests doesn't seem to know
about nilfs2.
