Thanks for including the demo program, Rui, it works for me (tm). Applied -- with the incremental patch below, which I think is correct because the only caller is bus.c, which is part of the base kernel, not a module. Modules will call acpi_bus_generate_event(), not acpi_bus_generate_genetlink_event() directly. thanks, -Len commit b563d6f30d937510e02541930b1558d0f5759413 Author: Len Brown <len.brown@xxxxxxxxx> Date: Tue Jul 3 15:32:23 2007 -0400 ACPI: netlink: remove unnecessary EXPORT_SYMBOL Signed-off-by: Len Brown <len.brown@xxxxxxxxx> diff --git a/drivers/acpi/event.c b/drivers/acpi/event.c index 98627b0..de4def9 100644 --- a/drivers/acpi/event.c +++ b/drivers/acpi/event.c @@ -221,7 +221,6 @@ int acpi_bus_generate_genetlink_event(struct acpi_device *device, "Failed to send a Genetlink message!\n")); return 0; } -EXPORT_SYMBOL(acpi_bus_generate_genetlink_event); static int acpi_event_genetlink_init(void) { @@ -245,7 +244,6 @@ int acpi_bus_generate_genetlink_event(struct acpi_device *device, u8 type, { return 0; } -EXPORT_SYMBOL(acpi_bus_generate_genetlink_event); static int acpi_event_genetlink_init(void) { - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
