Hi Linus,
Here's SLAB updates for 2.6.39-rc1. The interesting bits are SLUB lockless
fastpath patches from Christoph which improve performance and updates to
support bigger 'struct rcu_head' from Lai. I pulled the per-CPU tree to
slub/lockless which is why some already merged patches show up in the
pull request.
Pekka
