fs: convert writepage_t callback to pass a folio
Patch series "Convert writepage_t to use a folio".
More folioisation. I split out the mpage work from everything else
because it completely dominated the patch, but some implementations I just
converted outright.
This patch (of 2):
We always write back an entire folio, but that's currently passed as the
head page. Convert all filesystems that use write_cache_pages() to expect
a folio instead of a page.
