+config MD
+	bool "Multiple devices driver support (RAID and LVM)"
+	help
+	  Support multiple physical spindles through a single logical device.
+	  Required for RAID and logical volume management.
+
+config BLK_DEV_MD
+	tristate "RAID support"
+	depends on MD
+	---help---
+	  This driver lets you combine several hard disk partitions into one
+	  logical block device. This can be used to simply append one
+	  partition to another one or to combine several redundant hard disks
+	  into a RAID1/4/5 device so as to provide protection against hard
+	  disk failures. This is called "Software RAID" since the combining of
+	  the partitions is done by the kernel. "Hardware RAID" means that the
+	  combining is done by a dedicated controller; if you have such a
+	  controller, you do not need to say Y here.
+
+	  More information about Software RAID on Linux is contained in the
+	  Software RAID mini-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>. There you will also learn
+	  where to get the supporting user space utilities raidtools.
+
+	  If unsure, say N.
+
+config MD_LINEAR
+	tristate "Linear (append) mode"
+	depends on BLK_DEV_MD
+	---help---
+	  If you say Y here, then your multiple devices driver will be able to
+	  use the so-called linear mode, i.e. it will combine the hard disk
+	  partitions by simply appending one to the other.
+
+	  To compile this as a module, choose M here: the module
+	  will be called linear.
+
+	  If unsure, say Y.
+
+config MD_RAID0
+	tristate "RAID-0 (striping) mode"
+	depends on BLK_DEV_MD
+	---help---
+	  If you say Y here, then your multiple devices driver will be able to
+	  use the so-called raid0 mode, i.e. it will combine the hard disk
+	  partitions into one logical device in such a fashion as to fill them
+	  up evenly, one chunk here and one chunk there. This will increase
+	  the throughput rate if the partitions reside on distinct disks.

+

+
+config MD_RAID1
+	tristate "RAID-1 (mirroring) mode"
+	depends on BLK_DEV_MD
+	---help---
+	  A RAID-1 set consists of several disk drives which are exact copies
+	  of each other.  In the event of a mirror failure, the RAID driver
+	  will continue to use the operational mirrors in the set, providing
+	  an error free MD (multiple device) to the higher levels of the
+	  kernel.  In a set with N drives, the available space is the capacity
+	  of a single drive, and the set protects against a failure of (N - 1)
+	  drives.

+	  Software-RAID mini-HOWTO, available from

+
+	  If you want to use such a RAID-1 set, say Y.  To compile this code
+	  as a module, choose M here: the module will be called raid1.
+
+	  If unsure, say Y.
+
+config MD_RAID10
+	tristate "RAID-10 (mirrored striping) mode (EXPERIMENTAL)"
+	depends on BLK_DEV_MD && EXPERIMENTAL
+	---help---
+	  RAID-10 provides a combination of striping (RAID-0) and
+	  mirroring (RAID-1) with easier configuration and more flexable
+	  layout.
+	  Unlike RAID-0, but like RAID-1, RAID-10 requires all devices to
+	  be the same size (or at least, only as much as the smallest device
+	  will be used).
+	  RAID-10 provides a variety of layouts that provide different levels
+	  of redundancy and performance.
+
+	  RAID-10 requires mdadm-1.7.0 or later, available at:
+
+	  ftp://ftp.kernel.org/pub/linux/utils/raid/mdadm/
+
+	  If unsure, say Y.
+
+config MD_RAID5
+	tristate "RAID-4/RAID-5 mode"
+	depends on BLK_DEV_MD
+	---help---
+	  A RAID-5 set of N drives with a capacity of C MB per drive provides
+	  the capacity of C * (N - 1) MB, and protects against a failure
+	  of a single drive. For a given sector (row) number, (N - 1) drives
+	  contain data sectors, and one drive contains the parity protection.
+	  For a RAID-4 set, the parity blocks are present on a single drive,
+	  while a RAID-5 set distributes the parity across the drives in one
+	  of the available parity distribution methods.

+	  Software-RAID mini-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>. There you will also
+	  learn where to get the supporting user space utilities raidtools.
+
+	  If you want to use such a RAID-4/RAID-5 set, say Y.  To
+	  compile this code as a module, choose M here: the module
+	  will be called raid5.
+
+	  If unsure, say Y.
+
+config MD_RAID6
+	tristate "RAID-6 mode"
+	depends on BLK_DEV_MD
+	---help---
+	  A RAID-6 set of N drives with a capacity of C MB per drive
+	  provides the capacity of C * (N - 2) MB, and protects
+	  against a failure of any two drives. For a given sector
+	  (row) number, (N - 2) drives contain data sectors, and two
+	  drives contains two independent redundancy syndromes.  Like
+	  RAID-5, RAID-6 distributes the syndromes across the drives
+	  in one of the available parity distribution methods.
+
+	  RAID-6 requires mdadm-1.5.0 or later, available at:
+
+	  ftp://ftp.kernel.org/pub/linux/utils/raid/mdadm/
+
+	  If you want to use such a RAID-6 set, say Y.  To compile
+	  this code as a module, choose M here: the module will be
+	  called raid6.
+
+	  If unsure, say Y.
+
+config MD_MULTIPATH
+	tristate "Multipath I/O support"
+	depends on BLK_DEV_MD
+	help
+	  Multipath-IO is the ability of certain devices to address the same
+	  physical disk over multiple 'IO paths'. The code ensures that such
+	  paths can be defined and handled at runtime, and ensures that a
+	  transparent failover to the backup path(s) happens if a IO errors
+	  arrives on the primary path.
+
+	  If unsure, say N.
+
+config MD_FAULTY
+	tristate "Faulty test module for MD"
+	depends on BLK_DEV_MD
+	help
+	  The "faulty" module allows for a block device that occasionally returns
+	  read or write errors.  It is useful for testing.
+
+	  In unsure, say N.
+
+config BLK_DEV_DM
+	tristate "Device mapper support"
+	depends on MD
+	---help---
+	  Device-mapper is a low level volume manager.  It works by allowing
+	  people to specify mappings for ranges of logical sectors.  Various
+	  mapping types are available, in addition people may write their own
+	  modules containing custom mappings if they wish.
+
+	  Higher level volume managers such as LVM2 use this driver.
+
+	  To compile this as a module, choose M here: the module will be
+	  called dm-mod.
+
+	  If unsure, say N.
+
+config DM_CRYPT
+	tristate "Crypt target support"
+	depends on BLK_DEV_DM && EXPERIMENTAL
+	select CRYPTO
+	---help---
+	  This device-mapper target allows you to create a device that
+	  transparently encrypts the data on it. You'll need to activate
+	  the ciphers you're going to use in the cryptoapi configuration.
+
+	  Information on how to use dm-crypt can be found on
+
+	  <http://www.saout.de/misc/dm-crypt/>
+
+	  To compile this code as a module, choose M here: the module will
+	  be called dm-crypt.
+
+	  If unsure, say N.
+
+config DM_SNAPSHOT
+       tristate "Snapshot target (EXPERIMENTAL)"
+       depends on BLK_DEV_DM && EXPERIMENTAL
+       ---help---
+         Allow volume managers to take writeable snapshots of a device.
+
+config DM_MIRROR
+       tristate "Mirror target (EXPERIMENTAL)"
+       depends on BLK_DEV_DM && EXPERIMENTAL
+       ---help---
+         Allow volume managers to mirror logical volumes, also
+         needed for live data migration tools such as 'pvmove'.
+
+config DM_ZERO
+	tristate "Zero target (EXPERIMENTAL)"
+	depends on BLK_DEV_DM && EXPERIMENTAL
+	---help---
+	  A target that discards writes, and returns all zeroes for
+	  reads.  Useful in some recovery situations.
+
+config DM_MULTIPATH
+	tristate "Multipath target (EXPERIMENTAL)"
+	depends on BLK_DEV_DM && EXPERIMENTAL
+	---help---
+	  Allow volume managers to support multipath hardware.
+
+config DM_MULTIPATH_EMC
+	tristate "EMC CX/AX multipath support (EXPERIMENTAL)"
+	depends on DM_MULTIPATH && BLK_DEV_DM && EXPERIMENTAL
+	---help---
+	  Multipath support for EMC CX/AX series hardware.
