From 51a8cf9d2d97017d334f33f1b39067bd2f03bc49 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Tue, 10 Jul 2012 05:28:38 -0600 Subject: [PATCH] Btrfs: fix btrfs_is_free_space_inode to recognize btree inode For btree inode, its root is also 'tree root', so btree inode can be misunderstood as a free space inode. We should add one more check for btree inode.
