Could you please confirm that line 2221 in your disk-io.c looks like
this:

2219 int btrfs_free_fs_root(struct btrfs_fs_info *fs_info, struct
btrfs_root *root)
2220 {
2221         WARN_ON(!RB_EMPTY_ROOT(&root->inode_tree));
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2222         radix_tree_delete(&fs_info->fs_roots_radix,
2223                           (unsigned long)root->root_key.objectid);
2224         if (root->anon_super.s_dev) {
2225                 down_write(&root->anon_super.s_umount);
2226                 kill_anon_super(&root->anon_super);
2227         }

That's in the unmount path but not under write_ctree_supers, so I want
to make sure I'm looking at the right bug ;)
