Title:
  automount fails on resume after suspend if file open for writing

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  For a couple of years I have usually not shut down my pc after using it, I just leave it and let it suspend.
  (Of course I have also shut down the system completely every now and then.)
  This has worked well but recently with new kernels 4.2.0-* I get problems.

  Further investigations show that it is automount that fails when :
  1. a file is opened for writing on a nfs-mounted volume that autofs mounts
  2. autofs unmounts the nfs directory after five minutes of inactivity, AND
  3. the system is automatically suspended after ten minutes of inactivity

  After resuming activity it is impossible to access the volume on the
  server

  To reproduce:
      cat > /path/to/file/on/automounted/nfs-dir/file.txt
      write some text
      wait for the system to suspend

      Activate the system again and try to access the automounted volume
