There complete patch-set with my lru_lock splitting
plus all related preparations and cleanups rebased to next-20120210

On large systems we're also seeing lock contention on the lru_lock
without using memcgs. Any thoughts how this could be extended for this
situation too?

We can split lru_lock by pfn-based interleaving.
After all these cleanups it is very easy. I already have patch for this.

Cool. If you send it can try it out on a large system.

This would split the LRU by pfn too, correct?
