there is at least one technical reason to need more than one: certain types of storage (both big EMC boxes as well as solid state disks) don't behave like disks and have no seek penalty; any cpu time spent on avoiding seeks is wasted on those, so for these devices one really wants to use a different IO scheduler, one which is much lighter weight - 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/
