From a225800f322a3d6cc8b8b6c7dc4d5281f2f5375b Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 10 Jul 2024 15:45:32 -0400 Subject: fs: Convert aops->write_end to take a folio Most callers have a folio, and most implementations operate on a folio, so remove the conversion from folio->page->folio to fit through this interface.
