 In the changes, you have some code in iplopen() that runs once to
 initialise the locks. This looks fraught.
 
 What testing did you do that made this necessary?
 
 It would appear that the problem is iplopen() being called and trying
 to acquire locks before ipfattach() is called, correct?
 
 If such is the case then the locks need to be initialised somewhere
 else and not in ipfattach() - somewhere that is always called when
 the LKM loads and something similar for when ipfilter is compiled
 into the kernel.
