[Fix PATCH] ACPI/Button: Add ACPI Button event via netlink routine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit 1696d9d(ACPI: Remove the old /proc/acpi/event interface)
removes ACPI Button event which originally was sent to userspace via
/proc/acpi/event. This causes ACPI shutdown regression on gentoo
in the VirtualBox. Now ACPI events are sent to userspace via netlink.
This patch is to add ACPI Button event back via netlink routine.
