While looking at improving the saved_cmdlines cache I found a huge amount
of wasted memory that should be used for the cmdlines.
The tracing data saves pids during the trace. At sched switch, if a trace
occurred, it will save the comm of the task that did the trac

This will unregister the HW spinlock on module exit automatically for us,
currently we manually unregister which can be error-prone if not done in
the right order. This also allows us to remove the remove callback.
