213 This option enables the kernel userspace event layer, which is a
214 simple mechanism for kernel-to-user communication over a netlink
215 socket.
216 The goal of the kernel userspace events layer is to provide a simple
217 and efficient events system, that notifies userspace about kobject
218 state changes. This will enable applications to just listen for
219 events instead of polling system devices and files.
220 Hotplug events (kobject addition and removal) are also available on
221 the netlink socket in addition to the execution of /sbin/hotplug if
222 CONFIG_HOTPLUG is enabled.
