Subject: [PATCH] s390 (1/8): Kconfig.

- Use common drivers/block/Kconfig instead of own config options, move
s390 block device config options to drivers/s390/block/Kconfig and
include it from drivers/block/Kconfig.
- Fix configuration combination CONFIG_IPV6=m and CONFIG_QETH=y.

-config BLK_DEV_LOOP
- tristate "Loopback device support"
- ---help---
- Saying Y here will allow you to use a regular file as a block
- device; you can then create a file system on that block device and
- mount it just as you would mount other block devices such as hard
- drive partitions, CD-ROM drives or floppy drives. The loop devices
- are block special device files with major number 7 and typically
- called /dev/loop0, /dev/loop1 etc.
-
- This is useful if you want to check an ISO 9660 file system before
- burning the CD, or if you want to use floppy images without first
- writing them to floppy. Furthermore, some Linux distributions avoid
- the need for a dedicated Linux partition by keeping their complete
- root file system inside a DOS FAT file using this loop device
- driver.
-
- The loop device driver can also be used to "hide" a file system in a
- disk partition, floppy, or regular file, either using encryption
- (scrambling the data) or steganography (hiding the data in the low
- bits of, say, a sound file). This is also safe if the file resides
- on a remote file server. If you want to do this, you will first have
- to acquire and install a kernel patch from
- <ftp://ftp.kerneli.org/pub/kerneli/>, and then you need to
- say Y to this option.
-
- Note that alternative ways to use encrypted file systems are
- provided by the cfs package, which can be gotten from
- <ftp://ftp.kerneli.org/pub/kerneli/net-source/>, and the newer tcfs
- package, available at <http://tcfs.dia.unisa.it/>. You do not need
- to say Y here if you want to use one of these. However, using cfs
- requires saying Y to "NFS file system support" below while using
- tcfs requires applying a kernel patch. An alternative steganography
- solution is provided by StegFS, also available from
- <ftp://ftp.kerneli.org/pub/kerneli/net-source/>.
-
- To use the loop device, you need the losetup utility and a recent
- version of the mount program, both contained in the util-linux
- package. The location and current version number of util-linux is
- contained in the file <file:Documentation/Changes>.
-
- Note that this loop device has nothing to do with the loopback
- device used for network connections from the machine to itself.
-
- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. The module
- will be called loop.
-
- Most users will answer N here.
-
-config BLK_DEV_NBD
- tristate "Network block device support"
- depends on NET
- ---help---
- Saying Y here will allow your computer to be a client for network
- block devices, i.e. it will be able to use block devices exported by
- servers (mount file systems on them etc.). Communication between
- client and server works over TCP/IP networking, but to the client
- program this is hidden: it looks like a regular local file access to
- a block device special file such as /dev/nd0.
-
- Network block devices also allows you to run a block-device in
- userland (making server and client physically the same computer,
- communicating using the loopback network device).
-
- Read <file:Documentation/nbd.txt> for more information, especially
- about where to find the server code, which runs in user space and
- does not need special kernel support.
-
- Note that this has nothing to do with the network file systems NFS
- or Coda; you can say N here even if you intend to use NFS or Coda.
-
- If you want to compile this driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. The module
- will be called nbd.
-
- If unsure, say N.
-
-config BLK_DEV_RAM
- tristate "RAM disk support"
- ---help---
- Saying Y here will allow you to use a portion of your RAM memory as
- a block device, so that you can make file systems on it, read and
- write to it and do all the other things that you can do with normal
- block devices (such as hard drives). It is usually used to load and
- store a copy of a minimal root file system off of a floppy into RAM
- during the initial install of Linux.
-
- Note that the kernel command line option "ramdisk=XX" is now
- obsolete. For details, read <file:Documentation/ramdisk.txt>.
-
- If you want to compile this as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M and read <file:Documentation/modules.txt>. The module will be
- called rd.
-
- Most normal users won't need the RAM disk functionality, and can
- thus say N here.
-
-config BLK_DEV_RAM_SIZE

- The default value is 4096. Only change this if you know what are

-config BLK_DEV_INITRD
- bool "Initial RAM disk (initrd) support"
- depends on BLK_DEV_RAM=y
- help
- The initial RAM disk is a RAM disk that is loaded by the boot loader
- (loadlin or lilo) and that is mounted as root before the normal boot
- procedure. It is typically used to load modules needed to mount the
- "real" root file system, etc. See <file:Documentation/initrd.txt>
