Hi Mark, So you are saying that reverting that patch alone suffices to fix the problem that you are seeing? Firstly, a big "Thank You!!!" for testing the linux-next branch. I very much appreciate that you report the bugs before they get merged upstream. I'll have a look to see if I can find out what is the problem. The only significant change that patch should be introducing would be the use of xdr_stream_pos(). -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com ��.n��������+%������w��{.n�����{��w����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
