Description Jeff Layton 2007-11-09 20:45:33 UTC
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.
