Host supported TCQ only removes the pain from the software side, it still doesn't make it a fast techology. The only reason you would want to support that would be "it's easy, why not...". From my POV, I would refuse to support it just from an ideological standpoint :-) Legacy TCQ, hell no, not in a million years. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
