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.
