config RAW_DRIVER

        tristate "RAW driver (/dev/raw/rawN) (OBSOLETE)"

        help

          The raw driver permits block devices to be bound to /dev/raw/rawN.

          Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O.

          See the raw(8) manpage for more details.



          The raw driver is deprecated and will be removed soon.

          Applications should simply open the device (eg /dev/hda1)

          with the O_DIRECT flag.

          The maximum number of RAW devices that are supported.

          Default is 256. Increase this number in case you need lots of

          raw devices.
