[SCSI] osd_uld: OSD scsi ULD
Add a Linux driver module that registers as a SCSI ULD and probes for OSD type SCSI devices. When an OSD-type SCSI device is found a character device is created in the form of /dev/osdX - where X goes from 0 up to hard coded 64. The Major character device number used is 260.
