[PATCH 16/16] Fix compiling NFS when backporting writeback

[Stefan Bader]

BugLink: http://bugs.launchpad.net/bugs/585092

These changes were part of the following upstream commits:

  commit 7f2f12d963e7c33a93bfb0b22f0178eb1e6a4196
  Author: Trond Myklebust <Trond.Myklebust at netapp.com>

      NFS: Simplify nfs_wb_page()

  commit acdc53b2146c7ee67feb1f02f7bc3020126514b8
  Author: Trond Myklebust <Trond.Myklebust at netapp.com>
  Date:   Fri Feb 19 17:03:26 2010 -0800

      NFS: Replace __nfs_write_mapping with sync_inode()

As the changes above do some larger modifications on NFS, I am not sure
those should be part of the writeback backport.
