register_node() is defined as extern in include/linux/node.h. But the function is only called from register_one_node() in driver/base/node.c. So the patch defines register_node() as static.

/*

* include/linux/node.h - generic node definition
|
|
*
|
|
* This is mainly for topological representation. We define the
|
|
* basic 'struct node' here, which can be embedded in per-arch
|
|
* definitions of processors.
|
|
*
|
|
* Basic handling of the devices is done in drivers/base/node.c
|
|
* and system devices are handled in drivers/base/sys.c.
|
|
*
|
|
* Nodes are exported via driverfs in the class/node/devices/
|
|
* directory.
