OK. The issue appears to be that we have a variable with the same
name as a struct, as in:
struct rcu_state *rcu_state;
Of course, now I don't recall the details or the kernel version, other
than that the name change cleared things up. :-/

It does make it a bit easier for me when grepping through the source,
given the large number of "struct rcu_state" strings in there. And
yes, I should be using some more modern tools than "grep" and "cscope"!
But I am not the only throwback. ;-)
Thanx, Paul
