From 711f447b4fdf18b970e967469c6693577e9cc080 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 19 Jun 2022 08:07:05 +0200 Subject: [PATCH] btrfs: remove the finish_func argument to btrfs_mark_ordered_io_finished finish_func is always set to finish_ordered_fn, so remove it and also the now pointless and somewhat confusingly named __endio_write_update_ordered wrapper.
