Actually the current version of the patch does do some translation
(MODE_{SENSE,SELECT}_6 are mapped to their _10 equivalent, because
the _6 variants are not implemented by ATAPI/MMC devices), but a
better solution might be to move these translations up to transport
independant layers, and be handled through quirk entries, or some
similar flagging mechanism. After all, ATAPI really is a /transport/
mechanism for SCSI commands: it is up to the initiator of a request
to know which command set to use for a given device.
Thomas.
