Also, I think that it might be possible to get rid of RCU call in kmem cache destructor, because the cgroup subsystem already handles it and we could probably piggyback - see my comment to 5/7. Not sure if it's really necessary, since we already have RCU in SLUB, but worth looking into, I guess, as it might simplify the code a bit.
