2 * osd_uld.c - OSD Upper Layer Driver
3 *
4 * A Linux driver module that registers as a SCSI ULD and probes
5 * for OSD type SCSI devices.
6 * It's main function is to export osd devices to in-kernel users like
7 * osdfs and pNFS-objects-LD. It also provides one ioctl for running
8 * in Kernel tests.
