I need a support from the Linux SCSI subsystem for CDB length > 16 byte.
Is it possible to do that without recompiling the kernel with a new
MAX_COMMAND_SIZE definition.

It is hard to imagine any other way at the moment (definitely
in lk 2.4 and it is probably a bit late for lk 2.6).

Is there an upper limit on the size of the cdb you are interested in
(e.g. XDWRITE EXTENDED in SBC-2 is 64 bytes)?

How were you planning to pass the cdb (length > 16) to the kernel?
