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

- Say Y, unless you are building a system requiring minimal memory
- consumption.
