If I was a benchmark writer, I would not be willing running it as root to be able to mount/unmount, I would not be willing to require the customer creating special dedicated partitions for the benchmark, because this is too user-unfriendly. Or do I make incorrect assumptions? Not that I need this syscall and trying to sell the idea to anyone, just trying to understand the alternative you suggested. -- Best Regards, Artem Bityutskiy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
