+       help
+         Select this option if you want to use your expanded storage on S/390
+         or zSeries as a disk.  This is useful as a _fast_ swap device if you
+         want to access more than 2G of memory when running in 31 bit mode.
+         This option is also available as a module which will be called
+         xpram.  If unsure, say "N".

+       depends on CCW && BLOCK
+       select IOSCHED_DEADLINE
+       help
+         Enable this option if you want to access DASDs directly utilizing
+         S/390s channel subsystem commands. This is necessary for running
+         natively on a single image or an LPAR.
+
+config DASD_PROFILE
+       def_bool y
+       prompt "Profiling support for dasd devices"
+       depends on DASD
+       help
+         Enable this option if you want to see profiling information
+          in /proc/dasd/statistics.
+
+config DASD_ECKD
+       def_tristate y
+       prompt "Support for ECKD Disks"
+       depends on DASD
+       help
+         ECKD devices are the most commonly used devices. You should enable
+         this option unless you are very sure to have no ECKD device.
+
+config DASD_FBA
+       def_tristate y
+       prompt "Support for FBA  Disks"
+       depends on DASD
+       help
+         Select this option to be able to access FBA devices. It is safe to
+         say "Y".

+       prompt "Support for DIAG access to Disks"
+       depends on DASD
+       help
+         Select this option if you want to use Diagnose250 command to access
+         Disks under VM.  If you are not running under VM or unsure what it is,
+         say "N".

+       depends on DASD
+       help
+         This driver provides a character device interface to the
+         DASD extended error reporting. This is only needed if you want to
+         use applications written for the EER facility.

+config SCM_BLOCK

+       help
+         Block device driver for Storage Class Memory (SCM). This driver
+         provides a block device interface for each available SCM increment.
+
+         To compile this driver as a module, choose M here: the
+         module will be called scm_block.
