From d75855b4518b525dbba4e461819b26bc5bb89a82 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 1 Nov 2018 14:09:47 +0200 Subject: btrfs: Remove extent_io_ops::writepage_start_hook This hook is called only from __extent_writepage_io which is already called only from the data page writeout path. So there is no need to make an indirect call via extent_io_ops. This patch just removes the callback definition, exports the callback function and calls it directly at the only call site. Also give the function a more descriptive name. No functional changes.
