[Samba] cifs mounts fail after kernel upgrade

[Dale Schroeder]

Upgrading Debian testing's linux-image from 3.2.46-1 to 3.9.6-1 causes 
cifs mounts via fstab or command line to fail with return code -38 
"function not implemented".  Reverting back to the old kernel yields 
working cifs mounts.  The only option I use is a credentials file.  
Attempting the mount without this option does not work either.  Has 
anyone else seen this?

Thanks,
Dale
