+ bool "Deprecated /proc/acpi/event support"
+ depends on PROC_FS
+ ---help---
+ A user-space daemon, acpi, typically read /proc/acpi/event
+ and handled all ACPI sub-system generated events.
+
+ These events are now delivered to user-space via
+ either the input layer, or as netlink events.
+
+ This build option enables the old code for for legacy
+ user-space implementation. After some time, this will
+ be moved under CONFIG_ACPI_PROCFS, and then deleted.
