Now just signal the semaphore directly. http://bugzilla.kernel.org/show_bug.cgi?id=5534#c159 Signed-off-by: Len Brown --- diff --git a/drivers/acpi/events/evmisc.c b/drivers/acpi/events/evmisc.c index 6eef4efddcf..ee2a10bf907 100644 --- a/drivers/acpi/events/evmisc.c +++ b/drivers/acpi/events/evmisc.c @@ -342,20 +342,8 @@ static u32 acpi_ev_global_lock_handler(void *context) if (acquired) { /* Got the lock, now wake all threads waiting for it */ - acpi_gbl_global_lock_acquired = TRUE; - - /* Run the Global Lock thread which will signal all waiting threads */ - - status = - acpi_os_execute(OSL_GLOBAL_LOCK_HANDLER, - acpi_ev_global_lock_thread, context); - if (ACPI_FAILURE(status)) { - ACPI_EXCEPTION((AE_INFO, status, - "Could not queue Global Lock thread")); - - return (ACPI_INTERRUPT_NOT_HANDLED); - } + acpi_ev_global_lock_thread(context); } return (ACPI_INTERRUPT_HANDLED);
