Description Peter Trenholme 2012-09-10 13:17:12 EDT 
Description of problem:
An attempt to use a CIFS entry in the fstab having a "nofail" option produces an "unrecognized option" message, and, if the mount fails, a failure message is generated. (On a local network, failure can be expected if the target system is turned off.)

Version-Release number of selected component (if applicable):
5.6

How reproducible:
Every time

Steps to Reproduce:
1. Add a line in /etc/fstab for a cifs share with the "nofail" option specified.
2. Try to mount the share
3.
  
Actual results:
mount error(22): Invalid argument

Expected results:
Share mounted if available.

Additional info:
The bug is relatively minor since a "noauto" can be used, but it should be trivial to implement a "nofail."

The "nofail" option is listed as a "filesystem independent mount option" of the mount command, so it should be supported. (Output to stderr might be appropriate, but no error code should be reported,)

Note that, if the "noauto" is used, the share(s) need to be mounted after the boot completes.

Ok, patch sent to mailing list that seems to do the right thing:

    http://article.gmane.org/gmane.linux.kernel.cifs/7097

...if you could also test it, that would be helpful. I'll plan to commit it in a few days if no one objects.
