Dear all,

Thanks for discussing.
Against my expectations the story was aimed more generic goal. It is fine.


> Your patch affects the max_sectors attribute file for all devices, not just for tape devices.

Yes, I know my code is experimental.
It should check the type of a target device to affect only for tape devices.


> So there is no _tape_ device which can operate with larger block size.

But, usually, accepting very large block size is used to improve the
performance with a tape device.

So,,, at least about my circumstance, changing only scsiglue.c is a nice
solution.
