Subject: Re: [PATCH 1/9] extfat: remove ->writepage

2022-11-14 1:28 GMT+09:00, Christoph Hellwig <>:
> ->writepage is a very inefficient method to write back data, and only
> used through write_cache_pages or a a fallback when no ->migrate_folio
> method is present.
> Set ->migrate_folio to the generic buffer_head based helper, and remove
> the ->writepage implementation.
