From: Jeff Mahoney <jeffm@xxxxxxxx> Commit 60e4cf67a58 (reiserfs: fix extended attributes on the root directory) introduced a regression open_xa_root started returning -EOPNOTSUPP but it was not handled properly in reiserfs_for_each_xattr. When the reiserfs module is built without CONFIG_REISERFS_FS_XATTR, deleting an inode would result in a warning and chowning an inode would also result in a warning and then fail to complete. With CONFIG_REISERFS_FS_XATTR enabled, the xattr root would always be present for read-write operations. This commit handles -EOPNOSUPP in the same way -ENODATA is handled.
