CONFIG_KOBJECT_UEVENT: Kernel Userspace Events

General informations

The Linux kernel configuration item CONFIG_KOBJECT_UEVENT:

Help text

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 HOTPLUG is enabled.

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