Subject: [RFC 07/13] Uncached allocator: Handle memoryless nodes
Date: Thu, 14 Jun 2007 00:50:33 -0700	[thread overview]
Message-ID: <20070614075335.700401475@sgi.com> (raw)
In-Reply-To: 20070614075026.607300756@sgi.com

[-- Attachment #1: nodeless_mspec --]
[-- Type: text/plain, Size: 1776 bytes --]

The checks for node_online in the uncached allocator are made to make sure
that memory is available on these nodes. Thus switch all the checks to use
the node_memory and for_each_memory_node functions.
