From 14e04fb34ffa82ee61ae69f98d8fca12d2e8e31c Mon Sep 17 00:00:00 2001 From: Len Brown Date: Thu, 23 Aug 2007 15:20:26 -0400 Subject: ACPI: Schedule /proc/acpi/event for removal Schedule /proc/acpi/event for removal in 6 months. Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event() to make sure there is no confusion that it is for /proc/acpi/event only. Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event. There is no functional change if CONFIG_ACPI_PROC_EVENT=y Signed-off-by: Len Brown --- drivers/acpi/Kconfig | 14 ++++++++++++++ drivers/acpi/ac.c | 2 +- drivers/acpi/asus_acpi.c | 2 +- drivers/acpi/battery.c | 2 +- drivers/acpi/bus.c | 6 ++++-- drivers/acpi/button.c | 2 +- drivers/acpi/event.c | 6 ++++++ drivers/acpi/processor_core.c | 6 +++--- drivers/acpi/sbs.c | 2 +- drivers/acpi/thermal.c | 8 ++++---- drivers/acpi/video.c | 10 +++++----- 11 files changed, 41 insertions(+), 19 deletions(-) (limited to 'drivers/acpi') diff --git a/drivers/acpi/Kconfig b/drivers/acpi/Kconfig index f1372de4ce7..574259476fb 100644 --- a/drivers/acpi/Kconfig +++ b/drivers/acpi/Kconfig @@ -68,6 +68,20 @@ config ACPI_PROCFS Say N to delete /proc/acpi/ files that have moved to /sys/ +config ACPI_PROC_EVENT + 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.
