Title:
  NFSv4 stat(2) incorrect

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  We have encountered this bug, http://www.spinics.net/lists/linux-
  nfs/msg17801.html, which was discussed on the linux-nfs mailing list
  in December 2010.  I am reporting the bug here because the discussion
  on the linux-nfs mailing list seems to have fizzled out and resulted
  in nothing happening.  We are seeing the problem on Ubuntu 10.04
  running the 2.6.32-28-generic kernel.

  Please see the above link for full details of the problem.  We are
  able to consistently reproduce this problem exactly as described in
  that original problem report.  The only difference is that our NFS
  server is a NetApp FAS 2040 running ONTAP 8.0.1, whereas the original
  problem report was using a Solaris NFS server.

  I marked this bug as a regression since it does not affect older
  kernels, as described in the discussion on linux-nfs.  Indeed, we do
  not see this problem on CentOS 5.6 running the 2.6.18-238.12.1.el5
  kernel.  I do not know if this bug was not present in earlier kernels
  in Ubuntu, as we are recent Ubuntu converts.
