+config SCSI_OSD_INITIATOR
+       tristate "OSD-Initiator library"
+       depends on SCSI
+       help
+               Enable the OSD-Initiator library (libosd.ko).
+               NOTE: You must also select CRYPTO_SHA1 + CRYPTO_HMAC and their
+               dependencies
+
+config SCSI_OSD_ULD
+       tristate "OSD Upper Level driver"
+       depends on SCSI_OSD_INITIATOR
+       help
+               Build a SCSI upper layer driver that exports /dev/osdX devices
+               to user-mode for testing and controlling OSD devices. It is also
+               needed by exofs, for mounting an OSD based file system.
+
+config SCSI_OSD_DPRINT_SENSE
+    int "(0-2) When sense is returned, DEBUG print all sense descriptors"
+    default 1
+    depends on SCSI_OSD_INITIATOR
+    help
+        When a CHECK_CONDITION status is returned from a target, and a
+        sense-buffer is retrieved, turning this on will dump a full
+        sense-decoding message. Setting to 2 will also print recoverable
+        errors that might be regularly returned for some filesystem
+        operations.
+
+config SCSI_OSD_DEBUG
+       bool "Compile All OSD modules with lots of DEBUG prints"
+       default n
+       depends on SCSI_OSD_INITIATOR
+       help
+               OSD Code is populated with lots of OSD_DEBUG(..) printouts to
+               dmesg. Enable this if you found a bug and you want to help us
+               track the problem (see also MAINTAINERS). Setting this will also
+               force SCSI_OSD_DPRINT_SENSE=2.
