Subject: Re: [PATCH/RFC] slab: handle memoryless nodes efficiently
Date: Thu, 29 Oct 2009 17:30:09 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.1.10.0910291728200.30007@V090114053VZO-1> (raw)
In-Reply-To: <1256836094.16599.67.camel@useless.americas.hpqcorp.net>
Maybe better introduce an alternative to numa_node_id that refers to the
next memory node?
numa_mem_node_id?
We can then use that in various subsystems and could use it consistently
also in slab.c
One problem with such a scheme (and also this patch) is that multiple
memory nodes may be at the same distance to a processor on a memoryless
node. Should the allocation not take memory from any of these nodes?
