XFS_BUF_ORDERED instead of XFS_BUF_ISORDERED?

["Nathaniel W. Turner" <nate@houseofnate.net>]

Hi folks,

While doing a little light reading, I noticed the following in 
fs/xfs/xfs_log.c:1011 (in the 2.6.26.3 Linux kernel tree).  Am I missing 
something, or should XFS_BUF_ORDERED be replaced with XFS_BUF_ISORDERED 
in this check?

        if ((l->l_mp->m_flags & XFS_MOUNT_BARRIER) && 
!XFS_BUF_ORDERED(bp)) {
                l->l_mp->m_flags &= ~XFS_MOUNT_BARRIER;
                xfs_fs_cmn_err(CE_WARN, l->l_mp,
