Title:
  After upgrade to 3.13.0-35.62, rpc.gssd complains about missing
  /run/rpc_pipefs/gssd/clntXX/info

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed

Bug description:
  The following changes in 3.13.0-35.62:
   * sunrpc: create a new dummy pipe for gssd to hold open
     - LP: #1327563
   * sunrpc: replace sunrpc_net->gssd_running flag with a more reliable check
     - LP: #1327563
   * nfs: check if gssd is running before attempting to use krb5i auth in SETCLIENTID call
     - LP: #1327563
  are causing rpc.gssd to fill syslog with messages of the form
  ERROR: can't open /run/rpc_pipefs/gssd/clntXX/info: No such file or directory

  The problem was discussed last December in https://bugzilla.redhat.com/show_bug.cgi?id=1037793
  where the resolution was to include the following three patches:

  http://marc.info/?l=linux-nfs&m=138624689302466&w=2
  http://marc.info/?l=linux-nfs&m=138624684502447&w=2
  http://marc.info/?l=linux-nfs&m=138624684502447&w=2

  These patches are already in the upstream kernel (since 3.14). I suggest cherry-picking them for 3.13. Commit hashes from the 3.14 branch:
