It all looks like it should work (though it might make sense to include
<linux/rcupdate.h> and <linux/rculist.h>.  But I have to ask: do you
really need the added complexity of RCU here?  I suspect that TPM
devices don't come and go very often...once most of us have ripped it
out, we tend to leave it out...:)
