Comment # 14 on bug 934202 from Neil Brown

Created attachment 638854 [details]
New patch, better patch.

After discussing with upstream, I've discard that patch and have a new one.

I've tested this by hacking the Linux NFS server to give out the same sort of
delegations as the Netapp.
I can reproduce the error in the title, and this patch removes it.
I have committed to 'master' and 'opensuse-13.2', so it should appear in kotd
and future updates.  If you could test a latest kotd in a day of so that would
be great.
Once that is confirmed I would like this patch to go into SLES12.

This *doesn't* address the other error that has been reported:

> NFS: nfs4_handle_delegation_recall_error: unhandled error -10026.

and I don't think it addresses the state manager process spinning either.  I
need more details for those.  If they can be reproduced, the logs (like the
excellent ones which led to this patch) would help a lot.
