    Subject[PATCH 4/5] v2 Update sysfs node routines for new sysfs memory directories
    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.
