>Description:
	The problem has shown up after a mistake giving the arguments to
"mount". The first parts of source and target were identical:
mount zelnfs/... zelnfs   (Should be a nfs mount...)
This causes: "panic: locking against myself".

>How-To-Repeat:
	mkdir xxx
	mount xxx xxx
>Fix:
	One more parameter check?
