<div>Hello,</div>
<div>Its my fault,</div>
<div>Our kernel 2.6.30.9, however we migrated XFS to higher version 2.6.34</div>
<div> </div>
<div>We undo the XFS changes from commit 5fe878ae7f82fbf0830dbfaee4c5ca18f3aee442</div>
<div>because our fs/direct_io.c belong to version 2.6.30.9, and we do not want to change it.</div>
