I am somewhat confused about the role of MaxTransfer in the mountlist and startup message. I thought MaxTransfer was the largest request that the filesystem was supposed to issue to the device driver (say, hddisk.device) via a TD_READ command. I have been recently told that at least one large device-driver-writer interprets this to be the largest request that hddisk.device should issue to the hardware, implying that the FFS never needs to look at this field during normal operation (i.e., after mounting). Does anybody have an answer to this? Does FFS actually limit its requests to the size specified in MaxTransfer? -- Darren
