Subject: [PATCH 0/2] RE: NFSv4: truncate returns I/O error

Hi Miklos,

The base cause of the test failure was that the client was holding
onto a read delegation while trying to truncate the file. Whereas
some servers allow the client to do this (provided that nobody else
holds a read delegation), the Linux server does not, and returns
an error.
The fix is therefore to return the delegation if the server rejects
our attempt (see patch 2/2).

I've included patch 1/2 since it too was already queued for the
stable@...r.kernel.org queue, and so 2/2 has a dependency...

Thanks for the bug report!

Cheers
 Trond

Trond Myklebust (2):
  NFS: Properly handle the case where the delegation is revoked
  NFSv4: Return the delegation if the server returns NFS4ERR_OPENMODE
