[PATCH] fix try_module_get race in elevator_find This patch removes try_module_get race in elevator_find. try_module_get should always be called with the spinlock protecting what the module init/cleanup routines register/unregister to held. In the case of elevators, we should be holding elv_list to avoid it going away between spin_unlock_irq and try_module_get.
