From 0bf6368ee8f25826d0645c0f7a4f17c8845356a4 Mon Sep 17 00:00:00 2001 From: Lan Tianyu Date: Sat, 15 Mar 2014 13:37:13 -0400 Subject: [PATCH] ACPI / button: Add ACPI Button event via netlink routine Commit 1696d9d (ACPI: Remove the old /proc/acpi/event interface) removed ACPI Button event which originally was sent to userspace via /proc/acpi/event. This caused ACPI shutdown regression on gentoo in VirtualBox. Now ACPI events are sent to userspace via netlink, so add ACPI Button event back via netlink routine.
