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. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
