You're not wrong, but do we *really* want users to be able to submit 144115188075855872 I/Os with a single system call? How about limiting them to a single billion? Given that they have to allocate 64GB of *control* data structures to submit this many I/Os, I think this will be sufficient for many years to come. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
