From 7ce311d552e473a5176f8bb143fb45de64b8bd81 Mon Sep 17 00:00:00 2001 From: Gu JinXiang Date: Thu, 11 Jan 2018 16:12:18 +0800 Subject: btrfs: use reada direction enum instead of constant value in load_free_space_tree load_free_space_tree calls either function load_free_space_bitmaps or load_free_space_extents. And either of those two will lead to call btrfs_next_item. So in function load_free_space_tree, use READA_FORWARD to read forward ahead. This also changes the value from READA_BACK to READA_FORWARD, since according to the logic, it should reada_for_search forward, not backward.
