These are all the patches I've collected to date which enable filesystems to be converted to use folios. After applying these patches (on top of folio v12), I have an iomap (ie xfs/zonefs) conversion. I would expect filesystems to convert one-by-one, rather than converting all callers of (say) set_page_writeback() to call folio_start_writeback(). The biggest chunk of this is teaching the writeback code that folios may be larger than a single page, so there's no (or little) code reduction from these patches. Instead it takes us to where we can start preparing filesystems to see multi-page folios.
