From cd2e6024260de27a523e0af6ee47a20a6b8b8aa8 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 2 Dec 2022 11:26:42 +0100 Subject: [PATCH] hpfs: remove ->writepage ->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.
