Hello

just stepped over a kernel failure after stopping the openafs-client. The first
try stopping the daemon failed due to a still used mount point (umount: /afs:
device is busy). The next try caused the following kernel failure error:

I used a symbolic link on an afs directory of a used cell. Restarting and
stopping the service after the failure didn't result in another error. Though I
haven't restarted the system yet. Also, logging in and accessing the afs
directories after restarting the afs daemon causes no problems.
