Title:
  15 sec timeout when mounting with nfs4

Status in “linux” package in Ubuntu:
  Triaged
Status in Fedora:
  Unknown

Bug description:
  With the default nfs-common configuration (rpc.gssd not running),
  there is a 15 second delay when mounting an NFSv4 filesystem. After
  setting NEED_GSSD=yes and starting rpc.gssd, there is no delay.

  I don't know exactly when this was introduced. I reproduced it in
  trusty, in saucy, and in precise with the lts-saucy kernel, but not in
  raring.

  The patch series fixing this was merged recently and will be in 3.14:

  Not part of the original series, but there are a few fixes on top of
  those:

  Fedora and openSUSE have backported the fix to their 3.11-based
  kernels:
