Subject: [GIT PULL] SLAB changes for v2.6.39-rc1
Date: Tue, 22 Mar 2011 16:40:15 +0200 (EET) [thread overview]
Message-ID: <alpine.DEB.2.00.1103221635400.4521@tiger> (raw)
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
