** Description changed:

+ SRU Justification
+ 
+ Impact: A commit from upstream 4.4 stable introduced a regression in
+ refcounting auth_gss messages which can lead to an oops.
+ 
+ Fix: Cherry pick upstream commit
+ 1cded9d2974fe4fe339fc0ccd6638b80d465ab2c "SUNRPC: fix refcounting
+ problems with auth_gss messages."
+ 
+ Regresssion Potential: Test results confirm that the commit fixes an
+ existing regression. It's pretty straightforward and is already present
+ in some upstream stable kernels, so I think the potential for
+ regressions is minimal.

  On (K)ubuntu 16.04.01 (Xenial) Upgrading to kernel 4.4.0-57 the kernel
  crash on boot when in /etc/fstab a nfsv4 entry is active
  
  When comment the line or set to noauto the kernel boot with no error and
  mounting the nfs shares (after uncomment ) is also possible without
  error
  
  4.4.0-54 boots without this problem.
