I dunno. I seem to recall there was discussion about disk driver not flushing cache or something like that years ago but I could be imagining things. With recent kernels, there's no reason for userland to do that before shutting down. Kernel always flushes caches during shutdown, but we can also afford some paranoia there as that doesn't cause any harm. -- tejun - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
