As far as lockdep is concerned, we are not in an RCU read-side critical
section.

Very strange indeed.

One question -- is it possible that your kernel does not match your
source code?  I freely admit that it is extremely unlikely that such
a mismatch would happen to land on an rcu_dereference(), but...

Another unlikely possibility is that an interrupt occurred between
the rcu_read_lock() and the rcu_dereference(), and that this interrupt
had an extra unmatched rcu_read_unlock().

Color me confused!!!
