From 8cc0237abc3f138d9b5fa4cd8af26f3c335ba7eb Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 8 Nov 2018 10:18:07 +0200 Subject: btrfs: Remove extent_page_data argument from writepage_delalloc The only remaining use of the 'epd' argument in writepage_delalloc is to reference the extent_io_tree which was set in extent_writepages. Since it is guaranteed that page->mapping of any page passed to writepage_delalloc (and __extent_writepage as the sole caller) to be equal to that passed in extent_writepages we can directly get the io_tree via the already passed inode (which is also taken from page->mapping->host). No functional changes.
