  Although I haven't tested this myself, the original bug reporter
  provides a test case:

  2. start pulseaudio:

     E: [pulseaudio] core-util.c: Failed to create secure directory
     (/home/foo/bar/.pulse): Remote I/O error

  3. Actual Results:

     Expected Results:

      nfsd: correctly handle return value from nfsd_map_name_to_*

      commit 47c85291d3dd1a51501555000b90f8e281a0458e upstream.

  in kernel 2.6.32.30 fixes a regression introduced by commit
  3c726023402a2f3b28f49b9d90ebf9e71151157d.  However, this commit hasn't
  been backported to the 2.6.32 kernel.

  So, rather an fixing a regression, it introduces one and this patch
  should be reverted.
