Easily reproducible oops -- set up a CIFS share with anonymous auth. fstab entry something like this: //host/public /mnt/cifspub cifs guest,sec=none,noauto 0 0 ...mount it, and then try to mount it again. The second mount attempt will cause an oops. Attached patch has been sent upstream, but has not been committed yet.
