hm, this means the lock was taken twice by the same task: enabling
CONFIG_PROVE_LOCKING ought to tell us the precise locking info and
backtraces that causes this situation. I looked at the code and it wasnt
obvious at first sight. (we should only be holding cache_chain_mutex
here, and l3->list_lock should not be taken at this point.)
