Prev: [PATCH 05/25] atm: Convert pci_table entries to PCI_VDEVICE (if PCI_ANY_ID is used)
Next: [PATCH 8/8] sound: asihpi: fix sign bug
From: Nathan Fontenot on 15 Jul 2010 14:50 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.
