This was already mentioned when he sent it to linux-scsi a few days ago. There are scsi commands which bypass the block layer, such as SG_IO, and block layer stats can make an extremely busy disc look not busy. - 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/
