## ## Device nodes and interfaces for many basic system devices. ## ## ##

## This module creates the device node concept and provides ## the policy for many of the device files. Notable exceptions are ## the mass storage and terminal devices that are covered by other ## modules. ##

##

## This module creates the concept of a device node. That is a ## char or block device file, usually in /dev. All types that ## are used to label device nodes should use the dev_node macro. ##

##

## Additionally, this module controls access to three things: ##
