I think basically nothing in scsi.h needs to be exposed to userspace, only the ioctl defintions moved to scsi_ioctl.h earlier should. While userspace can use SCSI opcodes and status codes they are not a kernel ABI, but a protocol defintion. It isn't really the kernels job to export those, epecially as protocols evolve with new versions. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
