Well, the patch isn't quite correct because if it's not going to probe the cache it should set up a write through cache (or disabled cache) as the default. Patrick's patch http://marc.theaimsgroup.com/?l=linux-scsi&m=106366112221507 Does get this right. But my principle objection, as I've stated before, is that it isn't true that we don't need to manage the caches of hot pluggable devices, fibre channel being the counter example. Even for devices whose model is always forced remove, knowing the cache type is valuable information (especially as writeback cache type would be a rather grave error). The reason not to try to read the cache type for USB is that some of the devices barf on receiving the command. These type of devices are the ones we don't want to make any attempt to manage the cache for, and I'd like the flag name we settle on to reflect this. However, if there's no further objections on the naming front, I'll put Patrick's patch into the SCSI repository.
