The xfs_quota_priv header file is only included by xfs_qm header and there is no much users for its contents, hence we can move those stuff to xfs_qm header file and kill it. This patch also remove an unused macro DQFLAGTO_TYPESTR. Signed-off-by: Jie Liu <jeff.liu@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Ben Myers <bpm@sgi.com>
