From 1bda9dad5aa0199c8592bac32b91afbf8ea236ff Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 2 Dec 2022 11:26:44 +0100 Subject: omfs: 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.
