Hm, I don't see it: $ git grep -E '__(dev)?exit_p' linus/master:drivers/virtio/virtio.c $ Well, you could add something, but adding __devexit is a noop for most kernels. It matters only if you don't have CONFIG_HOTPLUG. In this series I only addressed drivers that use __{,dev}exit and __{,dev}exit_p inconsistenly. I.e. my script greps for __{,dev}exit_p and checks the prototype of the wrapped function. I have another script that does a similar check for platform_devices in general. This one also notices if you have a __devexit function that isn't wrapped by __devexit_p. So if you want to see drivers/virtio/virtio.c improving, send patches yourself :-) Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-K?nig | Industrial Linux Solutions | http://www.pengutronix.de/ | -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
