From 36273e5b4e3a934c6d346c8f0b16b97e018094af Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 13 Nov 2022 17:29:02 +0100 Subject: [PATCH] udf: remove ->writepage ->writepage is a very inefficient method to write back data, and only used through write_cache_pages or as a fallback when no ->migrate_folio method is present. Set ->migrate_folio to the generic buffer_head based helper, and remove the ->writepage implementation in extfat.
