This is likely a side effect of the real bug.

The print is likely this from the look_up_lock_class() function:
/*
* Huh! same key, different name? Did someone trample
* on some memory? We're most confused.
*/
WARN_ONCE(class->name != lock->name &&
lock->key != &__lockdep_no_validate__,
"Looking for class \"%s\" with key %ps, but found a different class \"%s\" with the same key\n",
lock->name, lock->key, class->name);
So it may be that the lock being passed in is corrupted.

The lock taken is from the passed in rcu_pending pointer.

Which has:
static void bkey_cached_free(struct btree_key_cache *bc,
struct bkey_cached *ck)
{
kfree(ck->k);
ck->k = NULL;
ck->u64s = 0;
six_unlock_write(&ck->c.lock);
six_unlock_intent(&ck->c.lock);
bool pcpu_readers = ck->c.lock.readers != NULL;
rcu_pending_enqueue(&bc->pending[pcpu_readers], &ck->rcu);
this_cpu_inc(*bc->nr_pending);
}
So if that bc->pending[pcpu_readers] gets corrupted in anyway, that could trigger this.
