Subject: [PATCH 4/5] v2 Update sysfs node routines for new sysfs memory directories
Date: Thu, 15 Jul 2010 13:40:40 -0500 [thread overview]
Message-ID: <4C3F5628.6030809@austin.ibm.com> (raw)
In-Reply-To: <4C3F53D1.3090001@austin.ibm.com>
Update the node sysfs directory routines that create
links to the memory sysfs directories under each node.
This update makes the node code aware that a memory sysfs
directory can cover multiple memory sections.
