+ depends on EXPERIMENTAL
+ ---help---
+ Saying Y here will enable generic SG (SCSI generic) v4 support
+ for any block device.
+
+ Unlike SG v3 (aka block/scsi_ioctl.c drivers/scsi/sg.c), SG v4
+ can handle complicated SCSI commands: tagged variable length cdbs
+ with bidirectional data transfers and generic request/response
+ protocols (e.g. Task Management Functions and SMP in Serial
+ Attached SCSI).
+
+ If unsure, say N.
+
+config BLK_DEV_INTEGRITY
+ bool "Block layer data integrity support"
+ ---help---
+ Some storage devices allow extra information to be
+ stored/retrieved to help protect the data. The block layer
+ data integrity option provides hooks which can be used by
+ filesystems to ensure better data integrity.
+
+ Say yes here if you have a storage device that provides the
+ T10/SCSI Data Integrity Field or the T13/ATA External Path
+ Protection. If in doubt, say N.
