Subject: Re: [patch 0/6] Per cpu structures for SLUB

Hi,

while I like this patch set I'm at odds with the interaction of this and
making the alloc/free fast paths lockless. 

The main race is s->cpu_slab[] and c->freelist. How does one close that
gap?

(btw, have you looked at my -rt slub patch?)
