We are making use of the lis_register_driver_qlock_option method to=0D
remove the qlock protection on some of our drivers and have some=0D
question on the correct way to use it.  If the driver is a clone driver=0D
I suspect that we would use the major number returned by the register=0D
call.  What is the queue locking state of the clone driver and do we=0D
need to control this also? =0D
=0D
Thanks
