Bug description:
  The nfs_can_extend_write function in fs/nfs/write.c in the Linux
  kernel before 3.13.3 relies on a write delegation to extend a write
  operation without a certain up-to-date verification, which allows
  local users to obtain sensitive information from kernel memory in
  opportunistic circumstances by writing to a file in an NFS filesystem
  and then reading the same file.

  Break-Fix: c7559663e42f4294ffe31fe159da6b6a66b35d61
