The test case for this bug is:

 	1. Get two computers (host A, host B) running the AFS client

 	2. Create a file in AFS (you can just use 'touch')

 	3. on host A, run a program that calls lockf() on this file, e.g.
 	   like this:

 		http://www-personal.engin.umich.edu/~wingc/openafs/code/lock.c

 	4. Now go to host B and delete the file.

 	5. Go back to host A and kill the program holding the lock

 	6. The kernel will now crash on host A (if host A is running the
 	   buggy version of OpenAFS)
